ESO7 Cartridge

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.
The ESO 7:

  • Reduces hardness in water that can cause minerals to buildup in coffee and espresso equipment
  • Reduces minerals such as calcium and magnesium
  • Reduces chlorine, off tastes and odors
  • Sanitary cartridge replacement is simple, quick and clean; internal filter parts are never exposed to handling or contamination

NOTE: No electrical connection required
