Installing a drinking water filter makes sense because it forms a barrier against dirt and particles entering your domestic water system. What many people don't know is a whole house filter is ideal for protecting drinking water supplies and appliances.
There are many water filters on the market, and all models are of state-of-the-art design to prevent particles such as rust and sand from ingressing your home's domestic water supply system. The pertinent standards even make installing such a filter mandatory for every home's domestic water supply system. But installation of the filter alone is only half the battle, as all filters have one thing in common: the filter elements aren't backflushed or replaced regularly because doing so is in many cases too complex a task. And this poses a major problem for hygiene in drinking water supply lines.
BWT has developed an ingenious solution with its BWT E1 single-lever filter – a protective filter offering innovative advantages in terms of convenience and hygiene. Replacing the hygiene vault (the filter cup containing the filter element) is so easy that consumers can do it themselves in a matter of seconds:
And all in less than 30 seconds.
BWT has effectively mitigated the hygiene risks associated with conventional filters, as you no longer have to touch any parts that come into contact with the water! What's more, the E1 prevents splashing when replacing the hygiene vault and the water pipe does not run dry.
The BWT E1 filter is available as the E1 HWS (domestic water station) including pressure reducer or as the E1 EHF (single-lever filter) for applications without pressure reducer.
Get your 10-year warranty!
With the E1 filter you no longer have to worry about forgetting to change the filter unit: An email notification tells you when the hygiene vault needs to be replaced. By registering your E1 single-lever filter you automatically receive a 10-year manufacturer's warranty.

Frequently asked questions about the BWT E1 single-lever filter
The DVGW is the German Association of Gas and Water Experts, which lays down, among other things, the guidelines for the construction, testing and use of plants for the treatment of drinking water. The ÖVGW is the Austrian counterpart. While WRAS does a similar job in the UK. Devices bearing these test marks comply to local standards and may be installed in drinking water installations without further measures. Only tested devices are subject to strict testing with regard to the materials used, and hygiene.
A GS mark, CE mark or similar alone are no proof of compliance with the applicable requirements with regard to hygiene and process success in drinking water.
