New improved version

Now fully made from stainless steel.

Since mid-2026, all HAHN Technology stainless steel water filters have been equipped with a newly developed connector made entirely from stainless steel.

In the past, the connector, switch lever and aerator were made from lighter materials to reduce weight. But customer feedback, our own standards and the desire to create an even more durable product pushed us to take the next step.

New stainless steel connector with switch lever and aerator

100% stainless steel

The housing, connector, switch lever and aerator are now fully made from stainless steel.

Built stronger

More stability, a more premium feel and a longer-lasting construction for everyday use.

Unique on the market

A faucet water filter focused on stainless steel, durability and a simple long-term solution.

We think long-term.

Production costs are higher and margins are lower. Still, we choose quality. Our goal is not to get rich quickly, but to become a market leader by offering the best, simplest and most durable solution. Longer-lasting products are also better for the planet: if something lasts longer, it needs to be replaced and produced less often.

Quick and tool-free installation in just a few minutes.

In most cases, simply unscrew the existing aerator, attach the filter system, and you're done.
If needed, screw on the appropriate adapter first and then attach the filter.

Please note that some faucets have an externally threaded aerator, while others use an internal (concealed) aerator. This can sometimes be difficult to recognize.
Make sure your aerator is removable before purchasing.

In rare cases, if the aerator has been tightened for a long time or is affected by limescale buildup, a wrench may be required to loosen it.
After removal, installation is straightforward.
