The Everpure QC7i Twin MH(2) System is part of the newest line of systems from Everpure, delivering superior filtration for premium quality water for coffee and high flow/high volume coffee applications. The 20" EV9613-21 MH(2) cartridge is specially designed to increase product life by inhibiting scale build-up and bacterial growth. Additionally, the system is engineered to feed the correct amount of scale inhibitor into each volume of water. The Micro-Pure II filtration media effectively inhibits bacterial growth, while the specialized activated carbon reduces chlorine taste/odor, and other offensive contaminants typically found in water.
