Why Stainless Steel is the Better Choice

Water acts as an abrasive: Conventional plastic filters release microplastics into your drinking water over time. Many of these filters are chrome-plated, giving them a metallic appearance, but are not real metal. HAHN Technology® stainless steel filters provide pure, uncontaminated water.

Before purchasing, please ensure that your aerator can be unscrewed.

Approximately 3–6 months of clean, great-tasting water.
Depending on water quality and daily usage, one cartridge filters around 2,000 liters.

In areas with heavily contaminated water, replacement may be required sooner.

It does not convert non-drinkable water into safe drinking water.

The system fits common M22 (female thread) and M24 (male thread) faucets.
To ensure maximum compatibility, the following adapters are included:

1× M22 to M24 adapter (male to male)
→ For faucets with M24 female thread

1× 20 mm female to M22 male adapter
→ For faucets with 20 mm male thread

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.
