The BWT besthead filter head is a wonderfully simple technical solution. It fits every BWT water+more standard filter cartridge and is a part of the initial installation. The unique, as-​necessary bypass setting is extremely simple to use and safe to operate due to the integrated locking mechanism.

Automatic shut off upon removal of a water cartridge makes changing the filter child's play. Two DVGW-​inspected check valves prevent water from flowing back into the water pipeline or the customer's water supply. BWT besthead, like all BWT components, is made from food-​safe materials and can be connected to all drinking water systems worldwide.
