Everpure Water Filter and Softener Cartridge - ESO 7
Unique three stage blending cartridge provides softened/buffered/precoat filtered water.
A small amount of carbon filtered water bypasses softening resin to maintain low TDS level, while a buffering agent prevents water from becoming too acidic. Reduces hardness that can cause scale build-up as well as particles, chlorine and other off tastes and odors. It may be used in single, twin, triple or quad head configurations.
