Designed for use with all varieties of BWT filter cartridges, the Filter Cartridge Head connects to your espresso machine through your water line. The filter head is compatible with any plumb-able espresso machine and uses 3/8" European threading. To prevent leaks and stop return flow along the supply pipe, the filter head is fitted with anti-backflow valves.

The filter head can be adjusted to one of several blend settings based on the hardness of your water. The blend settings adjust the amount of water run through the ion exchange in ratios of 0/100, 10/90, 25/75, and 40/60. When switching out filter cartridges, the filter head will cut the flow of water to prevent leaks.

Also available are 3/8" Hose Kits, 1/4" Adapters, and Aquameters, and the BestFlush Pressure Relief Valve.

The BWT Filter Cartridge Head is compatible for use with all varieties of BWT water filter cartridges including the Bestmax Premium and Besttaste.
