Point-of-use
APPLIED MEMBRANES INC pH Neutralization Calcite Filter Cartridge to Raise Alkalinity of Low pH Water | 4.5"x20" Fits 20" Housing | H-F4220CALCITE
APPLIED MEMBRANES INC.
- RAISE WATER pH – AMI Water pH Neutralization Cartridges naturally mineralize acidic drinking waters, raising the pH and alkalinity and restoring the balance to a neutral, non-corrosive equilibrium. Ideal for post treatment for a reverse osmosis system to remineralize RO water.
- DIMENSIONS – 4.5 inch Diameter x 20 inch Length. Universal calcite water filter replacement water filter cartridge fits #20 Filter Housing (Outside Dimensions of the Housing are Approximately 7.5” Dia. x 22”L)
- ALL NATURAL MINERALS: Made in mother nature, calcite is an all-natural mineral that is safe to drink and enhances the flavor of drinking water. With no fillers or additives, AMI calcite filter cartridges are filled with 100% pure calcite – and nothing else.
- REDUCE LEACHING & CORROSION: Calcite raises pH of water to a non-corrosive equilibrium, reducing leaching of metal plumbing components, appliances, and copper piping. Ideal for point of use or point of entry to treat water for use in espresso machines, ice makers, washing machines, water dispensers, and other appliances.
- SELF-LIMITING: Calcite has natural self-limiting characteristics. As the low pH water flows through cartridge dissolving the minerals, the pH of the water increases. Since neutral water does not dissolve calcite, the minerals stop dissolving when the water’s pH is corrected, giving you pH balanced water and a longer filter life.
