How does it work?

The BWT E1 Single-Lever Filter New utilises a single lever which shuts off the water supply, which relives any pressure whilst simultaneously releasing the hygiene vault (this is the filter cup that contains the filter element). The filter element is then removed so that it can be recycled along with your domestic waste.

The next step is to fit a new filter element by placing it into the hygiene cup – please remember to remove the filter from its sealed wrapper. Once the new filter is in place, the single lever can be pulled down resealing the filter housing and switching the water back on. This innovative approach ensures that the filter is changed regularly so that the integrity of the filter system is maintained. All in less than 30 seconds!

3 Easy Steps:

  1. Release the locking device, this will also shut off the water.
  2. Raise the lever and eject the filter cartridge automatically.
  3. Insert the new hygiene vault. Lower the lever. Lock. You’re good to go!

Installation in domestic water systems
A drinking water filter is installed downstream of any water meter and stops impurities from entering the home’s water supply ideally at the point where it enters the house.

Protection against particles and impurities
Dirt particles in your water can lead to dripping taps, damage pipes and household appliances. In a worst case scenario, pipework may even rupture due to corrosion.

Optimum drinking water hygiene
Particles deposited in pipelines are an ideal breeding ground for bacteria. A protective filter keeps out foreign bodies and thus ensures clean pipes and hygienic water.
