The Everpure BH² EV9612-50 Filter Cartridge provides clear, fresh, premium quality water for consistently great tasting coffee and beverages. Everpure's unique filter blend uses activated carbon to reduce chlorine taste and odor and other offensive contaminants. A self-contained scale inhibitor feed prevents limescale from forming in brewing equipment. Precoat submicron technology redues dirt and particles as small as 1/2 micron in size. This sanitary quick change cartridge is easy to install and replace. This BH² Everpure water filter cartridge replaces the old BH Everpure water filter and also fits into the QC4-BH head. It also replaces the EV9612-51, EV9612-00, EV961255, EV3107-51 part numbers.
