Unique 3-stage blending cartridge provides softened/buffered/filtered water. The ESO 7 Cartridge utilizes ion exchange resin with buffering capabilities and high capacity coconut carbon filtration. Buffering agent prevents water from becoming too acidic, and a small amount of carbon filtered water bypasses the softening resin to allow for proper initial hardness.
