Yes. As with any high-quality filter system, the ultranano-drink is designed for regular maintenance to ensure consistently high filter performance.

The filter must be replaced after 10,000 liters or after five years at the latest, provided the water hardness is 40 °fH or less. These intervals ensure that filtration remains reliable and consistent.

The ultranano-drink automatically notifies you when maintenance is due.

After approximately 10,000 liters of filtered water, or after 5 years at the latest, the filter emits an audible alert while in use.

At that point, maintenance should be performed within the next few months. During this process, the prefilter, the membranes, and the anti-germ filter are replaced to ensure that the filter’s performance remains at the intended level over the long term.

This ensures that the system operates reliably, efficiently, and with consistent quality at all times.

Yes. Maintaining the ultranano-drink is very easy and can be done on your own without any trouble.

Thanks to the bayonet lock, the filter can be replaced in just a few simple steps—the entire process usually takes about two minutes and requires no special tools.

The ultranano-drink systems are installed at any cold-water connection (angle valve) in the home—for example, in the kitchen, basement, or bathroom.

The systems are not installed directly on the house’s main water supply line, but rather on a suitable connection within the respective living unit. This allows for flexible installation tailored to local conditions.

For installation, you will need:

• a cold-water connection (angle valve) with a 3/8-inch male thread
• a nearby electrical outlet
• enough space for the filter system
• a waste siphon or drain connection

This ensures a professional and smooth installation.

Yes. In principle, you can also install the systems yourself. The decision on how to proceed with the installation is up to you.

However, to ensure optimal and long-term reliable operation, we recommend having the system installed by a qualified plumbing professional. This ensures that the connection is made properly and that you also receive an installation warranty from the company performing the work.

We provide a five-year warranty on all ultranano-drink systems, provided that the devices are properly installed and used as intended.

Upon request, the warranty can be extended for an additional five years for an extra charge. This allows you to benefit from a total of up to ten years of warranty coverage on your ultranano-drink.

Yes. The systems associated with the ultranano-drink are perfectly suitable for rental apartments. They can be installed without requiring any permanent changes to the apartment and can be removed without leaving any traces when you move out.

For rental apartments, however, we recommend a 3-in-1 or 4-in-1 combination wasserhahn (cold, hot, and filtered water in a single fixture). This solution requires no additional drilling and is particularly elegant. Such fixtures are available through dropvital or a plumbing specialist.

Alternatively, the filtered water can also be supplied via a small separate wasserhahn, which can be installed, for example, in place of a soap dispenser or a plug—again, without drilling a new hole.

The complete installation kit is included. The system can be disassembled and taken with you at any time, making it ideal for use in rental apartments.

The dropvital filter is designed to remove over 99% of common and known contaminants and harmful substances from trinkwasser. The filtration process used is among the most thorough available for household use and operates down to the lower nanometer range.

In independent, accredited Swiss laboratory tests, the dropvital filter was tested for several hundred defined contaminants. These tests demonstrated both the filter’s exceptional filtration depth and its targeted removal of PFAS and TFAS compounds.

The groups of substances proven to be filtered include, among others:

• Pesticides and their degradation products
• Fungicides and herbicides
• PFAS and TFAS compounds
• Residues of medications and antibiotics
• Micro- and nanoplastics
• Endocrine-disrupting trace substances
• Chlorinated byproducts

Filtration extends down to the nanometer range, which is significantly finer than many conventional filtration systems. This allows even very small, persistent molecules to be captured—molecules that cannot be reliably filtered using traditional activated carbon or pitcher filters.

dropvital’s performance specifications are not based on theoretical assumptions, but on concrete laboratory analyses conducted under defined test conditions. The actual filtration performance remains stable throughout the cartridge’s intended service life, provided that the recommended maintenance intervals are followed.

Many filter systems available on the market operate in the micrometer range and are therefore limited to larger particles. While such systems can reduce the taste of certain substances, they do not achieve the level of filtration required to remove modern trace substances.

Dropvital deliberately relies on high-precision filtration, which enables a measurable and reproducible reduction of over 99% of common and known contaminants—based on verified data rather than blanket advertising claims.

In short

Dropvital offers one of the deepest and most comprehensively tested filtration systems in the drinking water sector and removes over 99% of common and known contaminants that are relevant in modern water analyses.

The ultranano-drink uses Orbital Osmosis, a membrane-based filtration technology operating at the nanometer scale, which is comparable in its basic principle to reverse osmosis. At the same time, Orbital Osmosis differs significantly from conventional reverse osmosis systems in several key ways.

Orbital Osmosis is a patented technology; the term itself is protected. The goal of its development was to avoid the well-known disadvantages of reverse osmosis without sacrificing its filtration efficiency.

Comparison to Conventional Reverse Osmosis

As with reverse osmosis, Orbital Osmosis also uses a high-precision membrane. The difference, however, lies in how the membrane is used and in the system design.

Conventional reverse osmosis systems operate at high water pressure. The water is forced against the membrane, removing nearly all dissolved substances. While this process is technically effective, it has several drawbacks:

• high water consumption (often several liters of wastewater per liter of [trinkwasser])
• increased energy consumption
• complex maintenance and regular membrane cleaning
• limited membrane lifespan

Advantages of dropvital’s Orbital Osmosis Technology

Dropvital’s orbital osmosis membrane is designed so that the entire membrane surface is actively utilized. This achieves a very high filtration depth without forcing water through the membrane at high pressure.

Independent, accredited Swiss laboratory tests confirm the very high reduction of common and known contaminants. At the same time, the system is water-efficient: only one liter of tap water is needed to produce one liter of filtered drinking water.

The membrane is also designed for a long service life. Replacement is not required until approximately 10,000 liters have been filtered or after five years at the latest. With an average daily consumption of about six liters, this corresponds to a service life of about four and a half years.

Only food-grade materials are used for the drinking water system. The hoses meet high standards for hygiene and material purity and are sourced from applications similar to those used in sensitive technical environments.

Filtration Depth Comparison

The ultranano-drink filters contaminants down to the lower nanometer range. This filtration depth is significantly lower than what many alternative systems achieve.

By comparison:

Treatment methods such as ionizers alter the physical properties of the water but do not constitute true filtration. Most contaminants remain in the water.

In summary

Orbital Osmosis is not classic reverse osmosis, but rather an advanced, more efficient form of membrane-based drinking water filtration. It combines a very high filtration depth with low water consumption, a long service life, and high suitability for everyday use—without the typical drawbacks of conventional osmosis systems.

In many countries—including Germany and Switzerland—tap water is often described as one of the most strictly monitored food products. This statement is frequently simplified in public discourse and can be misleading.

Courts have pointed out that the term “most strictly monitored food product” suggests a level of absolute safety that does not actually exist. Legally, water suppliers’ responsibility generally extends only to the point of connection to the property. Beyond that point, water quality can be affected by in-home plumbing, stagnation times, faucets, or aerators. Even in the public water distribution system, contamination cannot be completely ruled out despite high standards.

What is tested is also a crucial factor. Tests of tap water—such as those conducted under the Drinking Water Ordinance—ensure that defined limit values are met. However, they do not prove that tap water is tested more frequently or more comprehensively than other foods, but merely that it complies with legal requirements.

Frequency of testing does not equal quality

The number of tests alone is not an indicator of quality. Tap water must be monitored regularly because it comes from groundwater and surface water and is often treated. Other types of water are subject to different regulations and testing protocols, which also set high standards but have different priorities.

Strict legal requirements apply to both tap water and other foods, with the goal of ensuring that products are safe for human health. The differences lie less in the level of safety and more in the type, timing, and scope of the inspections.

What does this mean for consumers?

Tap water in Europe is generally safe and of high quality. At the same time, regulatory oversight does not necessarily end where the water is actually consumed. The journey from the water treatment plant to the glass is long—and is influenced by infrastructure, home plumbing systems, and usage habits.

A drinking water filter does not replace the public water supply. However, it can provide an additional level of filtration directly at the waterhahn and help maintain consistent water quality regardless of external factors.

Conclusion

Food in Europe is subject to high safety standards. However, the claim that tap water is the “most strictly regulated food” is more of a simplistic advertising slogan than an objective statement of fact. What matters is not the label, but the quality of the water where it is consumed.

Dropvital is therefore not intended as a criticism of the public water supply, but rather as a complementary solution for anyone who desires additional transparency, control, and consistent water quality.

Tap water in Europe is generally safe and subject to legal controls. However, these controls are primarily carried out at the water treatment plant or up to the house connection—not necessarily where the water is actually consumed: at the waterhahn.

On its journey from the water treatment plant to the glass, water quality can be affected by in-home plumbing, fixtures, stagnation times, or deposits. The often-cited claim that tap water is the “most strictly regulated food” therefore falls short and does not accurately describe the actual situation at the point of use.

Furthermore, drinking water analyses are based on defined, known parameters. Trace substances, new chemical compounds, or substances without established limit values are not comprehensively monitored. Residues from agriculture, industry, or medicine also cannot always be fully monitored or removed using current technology.

Another factor is the in-home infrastructure. Materials such as copper, old metal pipes, or mineral deposits can further affect water quality over the final few meters. This so-called “last mile” lies outside the control of water utilities.

The ultranano-drink does not replace the public water supply. However, the system offers an additional, independent filtration stage directly at the water faucet. This filters the water right where it is actually used—regardless of pipe length, in-home plumbing, or regional differences.

Conclusion

We live in an environment where contaminants in the air, food, and water are ubiquitous. Ultra Nano Drink is designed as a complementary solution to specifically improve and maintain the quality of drinking water in everyday life—for everyone who wants to consume water in a conscious and controlled manner.

Mineral water is often seen as a high-quality alternative to tap water. However, there are several factors to consider when deciding between bottled water and a modern filtration system.

Regulatory Framework

Mineral water is subject to its own set of legal regulations, which differ from those for tap water. The requirements focus primarily on the original purity at the source. Tap water, on the other hand, is continuously monitored and tested for a variety of defined parameters. Both systems offer safety, but they take different approaches.

Packaging and Environmental Considerations

A large portion of mineral water is bottled in plastic bottles. These not only generate waste but can also—depending on storage conditions and material—leach contaminants into the water. While glass bottles are an alternative, their production, transportation, and recycling entail higher energy consumption and CO₂ emissions.

Everyday Practicality and Convenience

With the ultranano-drink, filtered drinking water is available directly from the tap at any time. This eliminates the need to regularly purchase, transport, and store bottles. This offers a significant increase in convenience, especially in everyday life.

Costs and Sustainability

In the long term, a filtration system is often more cost-effective than continuously buying bottled water. At the same time, packaging waste is significantly reduced, making the ultranano-drink a resource-efficient alternative.

Minerals are essential for the human body. However, it is not just the amount that matters, but above all the form in which minerals are absorbed.

Mineral Intake: Water or Food?

Minerals such as calcium and magnesium are present in varying concentrations in drinking water and mineral water. However, scientific studies show that the vast majority of our mineral intake comes from solid foods. Foods such as vegetables, fruits, nuts, and whole-grain products provide minerals in an organically bound, biologically readily available form.

Water primarily serves a different purpose: it provides hydration, transports substances throughout the body, and regulates physiological processes.

Organically vs. Inorganically Bound Minerals

Minerals from food are generally bound to organic structures, which facilitates their absorption. In drinking water, minerals are usually present in inorganic form. Although the body absorbs these minerals, it does not utilize them to the same extent, and excess amounts must be excreted via the kidneys.

For this reason, in nutritional science, water is not considered a primary source of minerals, but rather a medium that supports metabolism.

What does this mean for filtered water?

Dropvital filter systems are designed to reduce unwanted contaminants while retaining trace elements in the water. As a result, the water is not “distilled” and does not lose its natural composition; rather, it remains drinking water in the physiological sense.

Ultra-nanofiltered water is clearly distinct from distilled water. It still contains small amounts of dissolved trace elements and is suitable for daily fluid intake.

Classification from a Scientific Perspective

International organizations such as the WHO point out that no proven health benefits have been demonstrated for mineral-rich water. Likewise, there is no reliable evidence that water low in minerals has negative effects when part of a balanced diet.

A varied diet generally provides the body with all the necessary minerals. Water can therefore focus on its central function: hydration and supporting physiological processes.

What Do Scientists Say?

1. Nerbrand et al. (2003): The Influence of Calcium and Magnesium in Drinking Water on Cardiovascular Risk Factors
Summary: This study examined the association between elevated levels of calcium and magnesium in drinking water and cardiovascular risk factors in persons living in areas with soft and hard water. The results show that there is a significant association between elevated calcium concentrations in water and major cardiovascular risk factors, while magnesium in water or minerals in the diet did not show a comparable effect. This suggests that high calcium levels in drinking water could be a complex risk factor for cardiovascular disease.

2. Morr et al. (2006): Calcium Content in Bottled and Tap Water
Summary: This study examines calcium concentrations in bottled and tap water and their relevance to medical treatments. The results show that calcium content varies widely and typically ranges from only 8 to 20 mg/L in Russia’s “longevity zones.” This suggests that low calcium concentrations in drinking water may correlate with higher life expectancy.

3. Druzhyak (2005): Water for Health and Longevity
Summary: Druzhyak highlights that calcium concentrations in drinking water sources in regions of Russia with high life expectancy are extremely low (8–20 mg/L). This supports the hypothesis that a low mineral content in drinking water may contribute to health and longevity.

4. Siener et al. (2004): Mineral Water and the Risk of Calcium Oxalate Crystallization
Summary: This study investigated how mineral-rich water (with high concentrations of magnesium, calcium, and bicarbonate) affects urine composition. It was found that consuming such waters can increase the risk of calcium oxalate crystal formation. This suggests that a high mineral content in water may play a role in the development of urinary stones.

5. Bellizzi et al. (1998): Effect of Water Hardness on Kidney Stone Risk
Summary: This study analyzed the effects of hard and soft water on urine composition in patients with idiopathic nephrolithiasis. The results show that hard water significantly increases the concentration of calcium in urine, which raises the risk of calcium stone formation. Soft water (e.g., Fiuggi water) is considered more beneficial due to its lower risk profile.

These studies suggest that a low mineral content in drinking water could potentially be beneficial to health, particularly with regard to cardiovascular disease and kidney stones.

Minerals are essential for the human body. The key question, however, is to what extent [trinkwasser] actually contributes to daily mineral intake.

On behalf of Forum Trinkwasser e. V., scientists at the University of Paderborn, led by Professor Helmut Heseker, investigated the nutritional significance of drinking water for mineral intake. The results show that drinking water contributes only a limited amount toward meeting daily mineral requirements.

With an average consumption of about two liters of drinking water per day, the contribution to the recommended daily intake of calcium and magnesium, for example, is in the low single-digit percentage range. Many trace elements are either present in drinking water only in very small amounts or are of little relevance to the body when consumed in this way.

The study concludes that the primary source of minerals is solid food—particularly foods in which minerals are present in a biologically readily available, organically bound form.

From a nutritional science perspective, water therefore primarily serves a different function: it provides hydration, transports substances throughout the body, and supports physiological processes.

What does this mean for filtered water?

Dropvital filtration systems are designed to reduce unwanted contaminants without completely demineralizing the water. Trace elements remain in the water, while the filtration process is geared toward maintaining consistent and controlled water quality.

Filtered water is no substitute for a balanced diet—rather, it supports high-quality and easily digestible fluid intake in everyday life.

In summary

Minerals are important, but they are primarily obtained through food. Drinking water makes only a limited contribution to this. Dropvital therefore views filtration as a supplement that allows water to be used as a neutral, clean, and reliable medium in everyday life.

The scientific literature shows that there is no uniform, universally accepted target value for the mineral content in drinking water. Instead, numerous studies have examined the role that minerals in water play in comparison to total dietary intake, and how different mineral concentrations should be interpreted from a physiological perspective.

Several independent studies have focused in particular on calcium and magnesium in drinking water:

1. Nerbrand et al. (2003): The Influence of Calcium and Magnesium in Drinking Water on Cardiovascular Risk Factors
Summary: This study examined the association between elevated levels of calcium and magnesium in drinking water and cardiovascular risk factors in persons living in areas with soft and hard water. The results show that there is a significant association between elevated calcium concentrations in water and major cardiovascular risk factors, whereas magnesium in water or minerals in the diet did not show a comparable effect. This suggests that high calcium levels in drinking water could be a complex risk factor for cardiovascular disease.

2. Morr et al. (2006): Calcium Content in Bottled and Tap Water
Summary: This study examines calcium concentrations in bottled and tap water and their relevance to medical treatments. The results show that calcium levels vary widely and are typically only 8–20 mg/L in Russia’s “longevity zones.” This suggests that low calcium concentrations in drinking water may correlate with higher life expectancy.

3. Druzhyak (2005): Water for Health and Longevity
Summary: Druzhyak emphasizes that calcium concentrations in drinking water sources in regions of Russia with high life expectancy are extremely low (8–20 mg/L). This supports the hypothesis that a low mineral content in drinking water may contribute to health and longevity.

4. Siener et al. (2004): Mineral Water and the Risk of Calcium Oxalate Crystallization
Summary: This study investigated how mineral-rich water (with high concentrations of magnesium, calcium, and bicarbonate) affects urine composition. It was found that consuming such waters can increase the risk of calcium oxalate crystal formation. This suggests that a high mineral content in water could play a role in the development of urinary stones.

5. Bellizzi et al. (1998): Effect of Water Hardness on Kidney Stone Risk
Summary: This study analyzed the effects of hard and soft water on urine composition in patients with idiopathic nephrolithiasis. The results show that hard water significantly increases the calcium concentration in urine, which raises the risk of calcium stone formation. Soft water (e.g., Fiuggi water) is considered more beneficial due to its lower risk profile.

Scientific Context

From today’s perspective, there is no scientific consensus that a high mineral content in drinking water is inherently beneficial. Likewise, there is no universally accepted recommendation to specifically use drinking water as a source of minerals.

Rather, numerous studies indicate that the primary source of minerals is the diet. Drinking water serves primarily to replenish fluids, while minerals are predominantly absorbed from food in a form that is readily available to the body.

Water as a Central Component of the Body

The human body consists largely of water. This proportion varies depending on the stage of life: it is particularly high in infants, and in adulthood it accounts for well over half of body weight. These figures illustrate the central role water plays in fundamental bodily processes.

Water is also a ubiquitous component in nature. Plants, soil, and even solid materials contain bound water. For living systems, therefore, water is not a byproduct but a fundamental prerequisite.

Functions of Water in the Body

Water fulfills several essential functions in the human body:

• it serves as a transport medium and solvent
• it supports heat regulation and temperature balance
• it acts as a buffer and protective medium
• it facilitates the excretion of metabolic waste products

A large part of these processes depends on adequate and regular fluid intake.

Water Quality and Metabolic Processes

The kidneys process a large volume of fluid daily to maintain metabolic balance. In this process, substances the body does not need are excreted, while important components are retained.

The quality of the water consumed can influence which additional substances are introduced into the body. For this reason, not only the quantity but also the composition of the water plays a role.

Minerals in Water—A Matter of Classification

Minerals are essential for life. However, there is broad consensus in nutritional science that food is the primary source of minerals. Foods typically provide minerals in an organically bound form that the body can easily utilize.

In drinking water, minerals are predominantly present in inorganic form. These contribute only to a limited extent to daily mineral intake and do not fulfill any primary nutritional function in water. Water serves primarily as a fluid carrier, not as a source of nutrients.

What does this mean for modern drinking water?

High-quality drinking water should, first and foremost:

• be free of undesirable contaminants
• have a consistent composition
• reliably supply the body with fluid

Individual mineral requirements are met through a balanced diet. This allows water to focus on its central role: hydration and supporting physiological processes.

Classification for Filtered Water

Dropvital filter systems are designed to reduce unwanted substances without completely demineralizing the water. Trace elements are retained in small amounts, while the focus is on purity, stability, and suitability for everyday use.

dropvital makes no medical or therapeutic claims. Filtration is intended as a technical solution to provide water of consistent quality.

Conclusion

Water is essential for the human body. Its most important function is to hydrate the body, not to supply minerals. Being mindful of water quality can help ensure that water is used as a neutral, reliable medium in everyday life—as a complement to a balanced diet.

Ionizers are used to alter the pH of water and shift it toward an alkaline or acidic range. This is a form of water treatment, not traditional filtration.

Changes in pH

Ionizers affect the pH level of water. However, the human body has its own regulatory mechanisms for acid-base balance. Changing the pH level of drinking water does not replace these natural processes.

Filtration of Contaminants

Most ionizers are not designed to specifically remove contaminants. Often, simple pre-filters or activated carbon elements are used, which can only reduce larger particles or certain substances. Many dissolved contaminants, such as micropollutants, persistent chemicals, or microplastics, remain in the water.

Scientific Assessment

To date, there is no uniform scientific consensus regarding specific health benefits of ionized water. Water quality depends less on the pH level and more on the absence of undesirable contaminants.

Safety and System Selection

When choosing a water treatment system, it makes sense to rely on technologies whose filtration performance has been independently tested and that have been proven to remove specific contaminants. Systems with clearly defined filtration processes offer better comparability in this regard.

In summary

Ionizers alter the properties of water but do not constitute full-fledged filtration. Those who prioritize the targeted reduction of contaminants should opt for filtration systems that are specifically designed and tested for this purpose.

Advertisements for reverse osmosis systems often highlight extremely small pore sizes, such as 0.1 nanometers (0.0001 micrometers). However, this claim can easily lead to misunderstandings, as it does not describe how reverse osmosis membranes actually work.

Reverse osmosis membranes do not have open pores, as found in traditional filters or sieves. The separation layer consists of a dense polymer film (usually polyamide) applied to a stabilizing support layer. This active layer is amorphous and pore-free in the traditional sense.

Water transport therefore does not occur through pores, but rather via the so-called solution-diffusion mechanism. In this process, water molecules dissolve into the polymer structure of the membrane, diffuse through the material, and emerge on the other side. Larger molecules or those that are chemically incompatible are retained in the process.

By way of comparison:

A single water molecule has an effective diameter of about 0.27 nanometers. If a membrane actually had fixed pores measuring only 0.1 nanometers, even water could not pass through them. Such a membrane would be physically ineffective for water filtration.

The often-cited figure of “0.1 nanometers” is therefore not an actual measured pore size, but rather a simplified, calculated approximation derived from the retention rates of certain substances. It does not describe the actual structure of the membrane.

How does dropvital correctly communicate its filtration process?

We place great importance on technically sound and transparent information. Instead of theoretical pore sizes, we specify the membrane’s effective separation efficiency. This falls within the lower nanometer range and is based on:

• the actual material structure
• known molecular sizes
• measurements and independent tests

Thus, we are not describing a theoretical marketing concept, but rather the actual physical performance of the membrane technology used.

In summary

• Reverse osmosis membranes do not have conventional pores
• Claims such as “0.1 nanometer pore size” are simplified marketing figures
• Actual filtration is based on solution diffusion, not sieving
• dropvital deliberately communicates scientifically sound, realistic values

The ultranano-drink works effectively right from the start. However, for optimal and consistent filtration performance, we recommend letting the water run briefly first.

After the unit has been idle for more than a week, the membrane structure may relax slightly due to the lack of water pressure. This well-known physical phenomenon is referred to as the TDS effect. During this phase, filtration may temporarily not reach its optimal level.

For this reason, we recommend:

• After normal operation: pre-rinse for about 30 seconds
• After a prolonged period of inactivity (more than a week): pre-rinse for about 1 minute

After this brief pre-rinse, the system will resume operating at full, stable filtration capacity.

The pre-rinse water does not need to be discarded and can be used without any problems for watering plants or other common household purposes.

During the development of the ultranano-drink, special emphasis was placed on hygiene and long-term stability. Several technical measures help ensure that no germs can colonize or multiply within the system.

The system performs automatic flushing cycles at regular intervals to prevent stagnant water and reduce deposits. These flushing intervals exceed standard industry recommendations and help maintain consistent system hygiene.

The membrane technology used operates at the nanometer scale. Due to its structure, bacteria cannot pass through the membrane. At the same time, the uniform flow across the entire membrane surface ensures that deposits and localized contamination are minimized.

As an additional hygienic safety measure, a separate bacteria and virus filter is integrated into the system. This filter stage serves to hygienically stabilize the water after membrane filtration. The filtration performance of this safety stage has been tested and documented in independent tests conducted by the internationally recognized testing institute SGS.

Furthermore, materials suitable for drinking water are used throughout the system, and their surfaces are designed to make it difficult for biofilms to form. This reduces the risk of microbial contamination even during long-term operation.

The pH value indicates whether a liquid is acidic, neutral, or alkaline. Drinking water naturally falls within the slightly acidic to neutral range, which is completely normal from both a technical and sensory perspective.

Measurements typically show that the filtered water from the ultranano-drink has a pH value of around 6.5 to 7.0. This range also corresponds to the pH spectrum of many natural foods.

It is important to keep the following in mind:

The measured pH value of a beverage says nothing about how it is processed in the body. The human acid-base balance is regulated by complex metabolic processes and is not directly determined by the pH value of individual foods.

A frequently cited example is lemon juice. It has a distinctly acidic pH value, but is processed metabolically differently than its taste or measured value would suggest. This example shows that a food’s pH value is not a reliable indicator of its physiological classification.

Many fruits and vegetables also have pH values between about 5.5 and 7.5, without this affecting their quality or digestibility.

Systems for producing so-called alkaline water typically alter the water’s pH level by adding inorganic minerals or through electrolytic processes. This technically increases the water’s alkalinity. This change is often marketed as having health benefits, but it is controversial from a physiological perspective.

The human body does not depend on alkaline drinking water. The stomach, in particular, deliberately operates in a highly acidic environment with a pH of about 1.5 to 2. This acidity is essential for digestion, defending against germs, and absorbing nutrients. If alkaline liquids regularly enter the stomach, the body does not respond with relief but rather with a compensatory increase in acid production.

It is important to draw a clear distinction between alkaline water and natural foods. Alkaline water with pH levels above 8 and added inorganic minerals is not comparable to fresh fruits or vegetables. Plant-based foods contain organically bound minerals and typically have a pH range between about 5.5 and a maximum of 7. Their effect on metabolism follows entirely different biochemical mechanisms.

Scientific Assessment

The benefits of alkaline water are assessed inconsistently among experts. To date, there are no reliable long-term studies demonstrating a sustained health benefit from a permanently elevated pH in drinking water. The human acid-base balance is primarily regulated by the lungs, kidneys, and complex buffer systems. Drinking water plays only a minor role in this process.

It is known that water with a high calcium or magnesium content can have a higher pH value under certain conditions. However, no medical benefit can be inferred from this. Whether such a change is beneficial depends not on marketing claims but on physiological necessity—and this necessity generally does not exist in healthy individuals.

Criticism of Electrolytic Water Separation

The electrolytic separation of water into an acidic and a basic component is viewed critically by many experts. This artificial polarization corresponds neither to the natural composition of drinking water nor to the requirements of human physiology. Any health benefits are not scientifically substantiated.

Classification of Filter Technology at dropvital

Regardless of the pH value, reducing contaminants in drinking water is beneficial. High-quality filtration systems can reduce contaminants such as PFAS, heavy metals, pesticides, or pharmaceutical residues, thereby objectively improving water quality. From dropvital’s perspective, the focus is therefore not on pH manipulation, but on the purity, safety, and tolerability of the water.

A water filter can be beneficial. However, from today’s scientific perspective, targeted alkalization or electrolytic splitting of water is not necessary.

Expert Perspective

Critics in the fields of medicine and engineering have been pointing out for years that oversimplified concepts—such as “alkalizing” the body—do not do justice to the complexity of human physiology. The body regulates itself with high precision. External interventions via alkalized water are neither necessary nor proven to be effective.

Recommendation

Dropvital recommends basing the choice of a drinking water system on transparent criteria: reduction of contaminants, material quality, hygiene, and scientific evidence. Claims regarding the blanket alkalization of the body should be critically examined. Clean water is crucial. An artificially elevated pH level is not.

Dropvital active-drink is drinking water that is set in motion through a dynamic rotational flow using physical water enhancement. This process technically mimics the natural flow of a stream over a distance of approximately 30 kilometers. It is based on well-known hydrodynamic principles found in freely flowing bodies of water.

Through targeted rotation and flow guidance, the water acquires distinct flow dynamics. The chemical composition of the water remains completely unchanged. No minerals are added, nor are the pH value, hardness, or other chemical parameters affected.

Technological Approach

The physical enhancement is achieved through a precisely controlled flow system in which the water is set in rotation at high speed. This process generates a uniform, coherent movement of the water that is maintained for a certain period of time even after bottling, provided there is no renewed strong turbulence.

Unlike static methods or symbolic applications, dropvital active-drink is based on active flow dynamics. The simulation of a natural flow path serves to technically reproduce kinetic energy and flow order in the water.

Perception

Many people describe dropvital active-drink as having a particularly fresh, light, and lively mouthfeel. This perception is subjective and varies from person to person. It does not constitute a statement about health effects but refers exclusively to the sensory properties and the physical flow behavior of the water.

Clear Distinction

Dropvital active-drink is not a medical device or a dietary supplement. No claims are made regarding healing effects, therapeutic benefits, or health benefits. Statements regarding the naturalness or activity of the water refer exclusively to physical properties such as flow, movement, and dynamics.

Positioning

Dropvital active-drink is aimed at people who value high-quality water, modern engineering, and nature-inspired refinement. The focus is on purity, design, sensory experience, and a new way to consciously experience water—without chemical interventions and without medical claims.

Modern scientific research shows that water is not a static medium. Water molecules are in constant interaction via hydrogen bonds and are continuously reorganizing themselves. These temporary molecular arrangements are often described in the scientific literature as clusters or networks.

This dynamic is not an exception but a central characteristic of water. It influences fundamental physical properties such as flow behavior, solubility, and reaction kinetics.

Scientific Background

Studies using spectroscopic methods as well as molecular dynamics simulations confirm that water is a highly ordered yet extremely mobile system. The clusters described are not fixed structures, but rather snapshots within a continuous process.

It is precisely this constant reorganization that makes water a unique medium and explains why motion, flow, and energy input can measurably influence the behavior of water.

Context of Active Nanodrink

Dropvital Active Nanodrink builds on this scientific understanding and deliberately focuses on physical processes. Through controlled movement and flow dynamics, the water is brought into an active, dynamic state that is clearly distinct from still, static water.

The term “nano” refers to processes on the molecular and physical scale and does not describe any chemical change or the addition of substances. The chemical composition of the water remains unchanged.

Clear Distinction

Dropvital Active Nanodrink is neither a medical device nor a dietary supplement. No curative or therapeutic effects are promised. Statements regarding the activity or vitality of the water refer exclusively to physical properties such as movement, structure, and dynamics, as well as to sensory perceptions, which may vary from person to person.

Pioneering Work: Warner (1970)

In his groundbreaking article “Structured Water in Biological Systems” (Annual Reports in Medicinal Chemistry), Warner demonstrated that water in biological systems adopts ordered patterns. These patterns interact directly with biomolecular processes and underscore how central this organization is to living systems. 

Fundamental Models: Frank (1970)

Another groundbreaking paper in *science* analyzed the molecular structure of water and demonstrated how water molecules can organize themselves into dynamic, structural networks. Frank thus laid the foundation for understanding the multidimensional nature of water as a chemical and physical medium. 

Structural Networks: Neidle et al. (1980)

This paper in *Nature* demonstrated highly structured water networks in DNA-dinucleoside complexes. These networks reveal how water interacts with biological macromolecules at the molecular level and supports their stability and functionality. 

Specific Molecular Clusters: Kristinailyte et al. (2017)

Using NMR and FTIR techniques, this study in the *Journal of Molecular Liquids* investigated the clustering of water molecules. It showed that water forms nanoscale structures that change dynamically under various conditions and exhibit specific properties.  

Response to electromagnetic fields: Montagnier et al. (2015)

Nobel laureate Luc Montagnier and colleagues demonstrated that water has the ability to receive electromagnetic signals and store them in specific molecular arrangements. These findings expand our understanding of the active role of water in biological processes. 

Interactions due to external stimuli: Gramatikov et al. (1992)

In the *Fresenius Journal of Analytical Chemistry*, researchers investigated how external factors such as temperature or chemical changes influence the molecular organization of water. These studies demonstrate that water actively responds to environmental conditions and dynamically adapts its molecular structure. 

Networks and nonpolar substances: Muller (1988)

A study published in the *Journal of Solution Chemistry* demonstrated how water organizes itself around nonpolar molecules. These observations highlight the complexity of water’s molecular interactions. 

Quantum Effects in Water: Del Giudice et al. (2005)

In *Electromagnetic Biology and Medicine*, the authors introduced a model of coherent quantum electrodynamics. They demonstrated that the molecular organization of water is shaped not only by classical mechanisms such as hydrogen bonding but also by quantum physical phenomena. 

Surface interactions: Tarov et al. (2005)

This study demonstrated how hydrophobic and hydrophilic surfaces influence the molecular structure of water. The authors documented that water forms ordered layers when in contact with such surfaces, layers that are unique in their function. 

Electrical Properties: Tychinsky (2011)

In a comprehensive analysis published in the *Water Journal*, it was demonstrated that water molecules in specific arrangements exhibit an exceptionally high electrical susceptibility, indicating an extended molecular order.  

Spectral signatures: Segarra-Martí et al. (2013)

This study in *Molecular Physics* showed that molecular water organization generates specific absorption and fluorescence spectra that serve as molecular “fingerprints.” This points to the precision of structural dynamics in water.

Supramolecular Architectures: Elia et al. (2016)

Through targeted external stimulation, these authors created supramolecular architectures in water, as reported in the *Water* journal. These structures exhibit high stability and complexity that go far beyond simple molecular bonds. 

Hydrogen-Rich Water Clusters: Ignatov et al. (2024)

A recent study in *Water* investigates cluster formation in hydrogen-rich water (HRW) using NMR and DFT analyses. The results demonstrate the formation of stable cluster structures, further supporting the molecular dynamics and potential medical applications of structured water.

Hydrogen bonds are a central component of water’s structure and explain many of its well-known properties. However, modern research shows that they act in conjunction with other physical interactions, thereby enabling water’s unique dynamics and complexity.

In addition to hydrogen bonds, scientists consider the following influences, among others:

Van der Waals interactions

: These weak intermolecular forces contribute to the short-term stabilization of molecular arrangements and influence the spatial orientation of water molecules. They are a recognized component of physicochemical models used to describe collective effects in liquids.

Quantum physics approaches

Some theoretical studies, including models by Del Giudice and colleagues, investigate quantum physics effects as a complementary description of the molecular dynamics of water. These approaches extend classical models and are understood as part of an ongoing scientific discourse.

Electromagnetic influences

Research also addresses the question of how electromagnetic fields can influence the organization of water molecules. Such studies contribute to viewing water not only as a chemical substance but also as a physically responsive medium.

Surface

Interactions It is well established that hydrophilic and hydrophobic surfaces locally alter the arrangement of water molecules. Ordered structures emerge at interfaces that differ measurably from freely moving water and are relevant to many natural and technical processes.

Context and Significance

The research described is based on recognized experimental methods such as spectroscopy, computational modeling, and surface analysis. These studies consistently demonstrate that water is a dynamically organized system whose properties arise from the interplay of multiple physical forces.

This multidimensional perspective broadens the scientific understanding of water and explains why it plays a special role in biological, chemical, and technological contexts. It describes the adaptability and functionality of water without drawing any medical or therapeutic conclusions from it.

The growing interest in so-called structured water stems from an increasing awareness of just how central water is to biological processes. The human body consists largely of water, and a significant portion of it is found inside cells. In these highly organized environments, water is not isolated but is part of complex molecular interactions.

This observation gave rise to the idea that water might play a role not only chemically but also in terms of its physical organization. Terms such as “structured,” “hexagonal,” or “H3O2” water are used to describe this particular perspective on water.

Theoretical Foundations of the Concept

Proponents of structured water concepts assume that water molecules occasionally organize themselves into ordered arrangements and that movement, pressure, contact with surfaces, or natural flow can influence this organization. These considerations build on well-known physical properties of water, such as its dynamics, adaptability, and responsiveness to environmental conditions.

Connection to Nature and Spring Water

Structured water is often compared to natural spring water. Water that flows over long distances, comes into contact with rock, and is exposed to natural currents is often perceived as particularly fresh and vibrant. Such comparisons serve to illustrate natural processes in which movement and environmental influences shape the behavior of water.

This perception has contributed to many people taking a closer look at the quality and origin of their drinking water.

Popular Interpretations and Modern Lifestyles

The term “structured water” has also been adopted in the context of modern lifestyles, holistic approaches, and alternative ways of thinking. The focus here is less on medical effects and more on the conscious experience of water as a fundamental part of everyday life. Claims regarding detoxification, cellular health, or performance enhancement primarily reflect individual beliefs and are subject to varying scientific assessments.

Dropvital’s

Perspective Dropvital approaches the topic of structured water with an open yet responsible attitude. The focus is on physical properties such as the movement, dynamics, and purity of the water, as well as on high-quality, traceable refinement processes. Dropvital makes no claims regarding medical or therapeutic effects and understands terms such as “structure” or “activity” as descriptions of physical states and sensory perceptions.

Modern science does not describe water in biological systems as a random collection of individual molecules, but rather as a dynamic, locally organized medium. In human cells in particular, water in the immediate vicinity of biomolecules exhibits specific patterns of organization that are important for normal biological processes.

Ordered Layers of Water in Cells

In cells, water forms so-called hydration layers around proteins, DNA, and other large biomolecules. These water molecules are organized differently—both spatially and energetically—than freely moving water. Such structures are a well-studied component of biochemistry and support the stability, function, and interaction of biomolecular systems, for example in enzyme reactions or the structural organization of cellular components.

Classification of Modern Research Approaches

Some research approaches, including the concept of so-called “exclusion zone water,” investigate how water organizes itself in particular ways near surfaces or interfaces. These models provide exciting insights into the physical properties of water in complex environments and are being researched and discussed internationally. They contribute to furthering our understanding of water as an active component of biological systems.

Significance of Dynamics

A defining characteristic of water in cells is its high mobility and adaptability. Ordered layers of water are not rigid but change continuously in response to their environment. It is precisely this dynamism that enables biological systems to respond flexibly to varying demands and to efficiently control processes.

Positive Interpretation

Scientific findings show that water plays a far more complex role in biological systems than has long been assumed. Its ability to organize itself locally while remaining highly dynamic makes water a central element of life. This perspective underscores the special significance of water without deriving any medical or therapeutic conclusions from it.

Dropvital’s

Approach Dropvital embraces this modern understanding of water as a dynamic and adaptable system. Terms such as “structure” or “organization” are understood here as descriptions of physical states and natural processes. Dropvital makes no claims regarding healing effects or health benefits and consciously prioritizes transparency and scientific rigor.

Summary

Research shows that water in human cells is locally organized and, at the same time, highly dynamic. These properties support fundamental biological processes and illustrate how versatile water is as a medium. In this sense, dropvital views water as a fascinating, living system whose complexity is increasingly being understood scientifically.

UV light is frequently used in water treatment to reduce microorganisms. It is a well-established method for ensuring water safety. At the same time, UV treatment is limited to this purpose and does not alter either the chemical composition or the physical dynamics of the water.

With active-drink, dropvital takes a deliberately different approach. The focus is not on treating the water with high-energy radiation, but rather on a gentle, physical refinement process modeled after natural movement and flow processes.

Focus

on Movement and Dynamics active-drink is based on the idea of viewing water not as a static medium, but as a dynamic system. Through targeted physical processes, the water is set into active, uniform motion. The chemical composition of the water remains completely unchanged in the process. No substances are added or removed.

This approach is modeled after natural flow processes, such as those found in freely moving water, and aims to shape the physical properties of the water in a particularly gentle manner.

Radiation-Free Approach

dropvital deliberately avoids the use of UV radiation in the refinement of active-drink. This eliminates high-energy interventions that go beyond mere hygiene. Instead, dropvital relies on transparent, reproducible physical principles such as movement, flow, and contact time.

Classification of Scientific Concepts

In research, water is increasingly described as a complex, reactive system whose properties depend heavily on movement and the environment. These findings form the conceptual basis of active-drink. However, dropvital does not derive any medical or therapeutic claims from them.

Clear Distinction

: active-drink is neither a medical device nor a dietary supplement. No claims are made regarding effects on cells, DNA, the immune system, or diseases. Statements regarding quality, activity, or naturalness refer exclusively to the physical properties and sensory perception of the water.

Summary:

dropvital active-drink represents a modern, radiation-free water enhancement process that relies on physical movement rather than irradiation. The focus is on purity, dynamism, and a mindful approach to water—clear, transparent, and without any promises of medical efficacy.

No. When installed properly, the active-drink is completely service- and maintenance-free. If it is integrated into the cold-water system in accordance with specifications and operated in conjunction with a suitable filtration system, neither regular maintenance nor replacement is required.

The active-drink operates purely on physical principles, contains no wear parts, and requires no consumables. As a result, it remains fully functional over the long term without the need for ongoing intervention.

The physical treatment in the active-drink sets the water in motion with intense, uniform movement. This dynamic action increases the mixing of the water and can promote contact with the ambient air, especially as it flows from the faucet.

Under certain conditions, this can lead to a slightly increased concentration of dissolved oxygen in the water. Measured values may vary depending on water temperature, source water, and flow rate.

active-drink does not add oxygen to the water and does not alter its chemical composition. Any observed differences relate exclusively to physical properties such as movement, mixing, and gas solubility.

Note on Interpretation

: Information regarding dissolved oxygen refers to measurable physical parameters of the water. It does not imply any biological, health-related, or performance-related effects.

The physical dynamics of the water generated by active-drink are retained for a certain period of time after bottling, particularly when stored undisturbed in a closed container. How long these properties remain detectable depends on factors such as movement, temperature, and storage conditions.

Unlike purely static methods, active-drink is based on the active movement of the water, which allows its physical quality to be evident not only immediately within the system but also after bottling.

Due to its polar molecular structure and the formation of hydrogen bonds, water exhibits complex and dynamic behavior. In addition to hydrogen bonds, other physical forces—such as van der Waals and dipole-dipole interactions—are at work. These properties make water a system that continuously organizes and realigns itself at the molecular level.

For decades, scientific research has described so-called water clusters—temporary arrangements of several water molecules—that form under certain physical and chemical conditions.

Scientific Evidence and Methods

The existence and behavior of water clusters have been investigated using established experimental and theoretical methods:

• Oka et al. (2019) demonstrated in a hydrophobic environment that signals from water clusters remain detectable for up to three days.

• Kulkarni (2021) used density functional theory (DFT) to analyze the stability of water clusters as a function of the number of hydrogen bonds.

• Kristinaityte et al. (2017) investigated dimer, tetramer, and hexamer water clusters using nuclear magnetic resonance (NMR) and infrared spectroscopy (FTIR).

• Sun et al. (2017) and Yang et al. (2020) demonstrated that NMR-based parameters allow conclusions to be drawn about the number of water molecules and hydrogen bonds in water clusters.

These studies confirm that water can form preferred molecular arrangements without these being permanently fixed structures.

Cluster Sizes and Molecular Organization

The scientific literature describes clusters consisting of two, drei, vier, and more water molecules. Configurations with six molecules are particularly frequently modeled as energetically favorable. In addition, larger arrangements with up to 30 water molecules have been observed, representing combinations of hexagonal and smaller structures.

Influence of Minerals and Ions

The local organization of water is also influenced by dissolved ions:

• Water clusters around calcium ions have been studied by Kochanski & Constantin (1987), Watanabe & Iwata (1997), and Ariyarathna & Miliordos (2020), among others.

• Cluster formation involving magnesium ions was described by Delgado, Sethio & Kraka (2021).

• Wang et al. (2023) analyzed water clusters in association with zinc ions (Zn²⁺).

These studies show that stable hydrate shells composed of water molecules can form around metal ions, as is typical for natural drinking water.

Influence of External Fields

External physical influences were also investigated:

• Chang & Weng (2006) showed that the number of hydrogen bonds increases when exposed to constant magnetic fields between 1 and 10 tesla.

• Gao et al. (2021) demonstrated, using molecular dynamics simulations, that changes in the cluster structure can be maintained over time. The analysis was performed using hierarchical clustering methods.

Conclusion

The studies cited demonstrate that water forms temporarily organized molecular structures under certain conditions. These structures are dynamic, environment-dependent, and part of a constantly readjusting equilibrium. No conclusions regarding permanently fixed water structures or specific health effects can be drawn from this.

Context at dropvital

Dropvital refers to these scientific findings as an expression of a modern physical understanding of water. The term “structured water” is used here as a simplified description of complex molecular dynamics. Dropvital makes no medical or therapeutic claims and does not derive any health claims from the studies mentioned.

Dropvital’s treated water undergoes purely physical treatment. Its chemical composition remains unchanged; no substances are added or removed. In principle, it is therefore also suitable for babies and toddlers, provided that the source drinking water meets the usual quality standards.

In scientific and technical literature, water in the human body is often described as having a particularly ordered structure. For example, the book *The Water Puzzle and the Hexagonal Key* argues that water in biological systems—particularly in newborns—exists predominantly in ordered molecular arrangements. This description serves to illustrate the biological organization of water and does not constitute a medically recognized standard or recommendation.

Dropvital incorporates such perspectives as part of a broader understanding of water, without drawing conclusions about health effects or benefits from them. Statements regarding babies and toddlers refer exclusively to the physical integrity and tolerability of the water, not to promises regarding development, health, or vitality.

As with all drinking water for infants, the following applies: In cases of specific health concerns or when preparing baby food, the general recommendations of healthcare professionals should be followed.
