There are many filters on the market - all variants are state of the art to keep particles such as rust particles and sand grains away from the domestic installation. The installation of a filter in every domestic installation is even mandatory according to the relevant standards. But installation alone is only half the battle, because all filters unfortunately have one thing in common: the filter elements are not regularly backwashed or changed because it is often too complicated. And that is a big problem for the hygiene of drinking water pipes.
BWT has developed an ingenious solution for this: The BWT E1 single-lever filter - a protective filter with innovative comfort and hygiene benefits. Replacing the hygiene vault (this is the filter cup with the filter element) is so easy that the consumer can do it himself in just a few seconds.

• Unlock the safety catch and thus simultaneously shut off the water
• Pull up the lever and thus automatically eject the hygiene safe
• Insert the new hygiene safe. Close the lever. Lock. Done!

And all this in less than 30 seconds.
In this way, BWT has defused the hygiene risks of conventional filters, water-affected parts are no longer touched! In addition, the E1 also avoids splashing water when replacing the hygiene safe and the water pipe does not run empty. The BWT E1 filter is available as E1 HWS(domestic water station) incl. Pressure reducer or as E1 EHF (single lever filter) for applications without pressure reducer.
