Clean drinking water straight from the tap—no chemicals, no installation required, no compromises. dropvital’s nano-tap was named the winner of the 2026 Green Product Award in the consumer goods category. In this article, you’ll learn what this award represents, why it’s significant, and how the nano-tap can benefit your everyday life.
What is the Green Product Award?
The Green Product Award is one of the most prestigious design awards for sustainable products in the German-speaking world. For years, it has honored products that combine environmental responsibility with functional, well-thought-out design. The jury doesn’t just evaluate the final product—it considers the entire life cycle: raw materials, manufacturing, service life, reparability, and recycling at the end of the product’s life.
This sets the award apart from a traditional design award. Beautiful design alone is not enough. A product must demonstrably be more sustainable than the market standard—in its impact, its choice of materials, and its contribution to society.
The fact that the nano-tap emerged as the 2026 winner in this competition is by no means a given.
Drinking Water in Germany, Austria, and Switzerland—Good, but Not Without Concerns
Tap water in the DACH region is generally considered to be tested and safe to drink. The water utilities are doing a good job. And yet: the challenges to water quality are increasing.
PFAS—so-called “forever chemicals”
They enter groundwater via agriculture, industry, and landfills. They are chemically stable, accumulate in the body, and are suspected of posing long-term health risks. Limit values have been tightened in recent years, but residues remain detectable.
Microplastics
Microplastics are now found in nearly every water source. Plastic particles enter the water through environmental sources, as well as through aging pipeline systems and plastic packaging.
Pharmaceutical residues, nitrates, and heavy metals
These are additional contaminants that vary by region and are not completely eliminated by conventional drinking water treatment.
The result in many households: plastic bottles. In Germany, Austria, and Switzerland, billions of liters of water are purchased in single-use plastic bottles every year—at a significant environmental cost. Yet in most regions, tap water is of comparable or better quality. You don’t need a bottle. You need the right filter.
What is the nano-tap—and how does it work?
The nano-tap is a compact, chemical-free drinking water filtration system that is installed directly on the waterhahn. It requires neither a special faucet nor an electrical connection. Installation is tool-free—it takes just a few minutes and requires no technical expertise.
That sounds simple. And it is. But behind this simplicity lies precise filtration technology.
The nano-tap has been proven to reduce:
- PFAS (per- and polyfluoroalkyl substances)
- microplastics
- Other organic and inorganic contaminants
What it does not remove:
Essential minerals such as calcium and magnesium are retained. The filter works selectively—it reduces contaminants without stripping the water of its natural mineral structure. This is a key difference from reverse osmosis systems, which filter very thoroughly but also remove valuable minerals in the process.
Why the nano-tap is sustainable—and not just a name
The word “sustainable” is overused in the world of products. With the nano-tap, it’s a proven fact.
Durability Instead of a Disposable Mindset
The nano-tap is designed for durability. While water filter cartridges from other systems are discarded after just a few weeks, the nano-tap is engineered to remain in use for the long term and can be recycled at the end of its service life.
Drastically fewer plastic bottles
A household that switches to the nano-tap significantly reduces its consumption of plastic bottles. Extrapolated over several years and across millions of users, this results in a measurable contribution to reducing plastic waste—not as a promise, but as a direct consequence of using the product.
No electricity, no chemicals
The nano-tap operates without electricity or chemical additives. This minimizes its environmental footprint during operation.
Tool-free installation
No specialist required, no travel, no hassle—installation by the user themselves further reduces the CO₂ emissions associated with the product.
It was precisely this combination that convinced the Green Product Award jury.
What the award means for you as a user
Anyone buying a water filter faces a bewildering array of choices. Systems vary considerably in technology, price, installation complexity, and effectiveness. Marketing claims are often easier to find than reliable facts.
The Green Product Award is an independent evaluation by an external panel of experts. It provides guidance. When a product is named a winner, it means that third parties have tested it—based on criteria that go beyond mere appearance.
For you as a consumer, this provides a more reliable basis for decision-making than an advertising claim.
dropvital – Water with a Purpose
Dropvital develops water filtration systems for households and businesses in the DACH region. The approach is clear: drinking water should be demonstrably better—through technology that works and products that are honest.
For us, the Green Product Award 2026 is a confirmation that we’re on the right path. It’s not an endpoint, but a benchmark against which we’ll continue to measure ourselves.
Conclusion: Clean water starts at the tap
Anyone thinking about clean drinking water today doesn’t necessarily have to resort to plastic bottles or undertake expensive renovations. The nano-tap shows that there’s another way: uncomplicated, suitable for everyday use, sustainable—and now also independently recognized.
If you’d like to know how the nano-tap works, exactly what its filtration performance is, and how the installation process works, you’ll find all the details on the product page.
