Calcite Filter Cartridges for Neutralizing Low pH Water

pH Neutralizer Cartridge - 100% Calcite - For 20" Standard Filter Housing

AMI calcite filter cartridges are filled with 100% calcite media to naturally remineralize acidic drinking waters, raising the pH and alkalinity to a non-corrosive equilibrium.  Calcite, a naturally occurring mineral, is self-limiting - dissolving only enough to increase the water's alkalinity to reach a non-aggressive, non-corrosive level.  AMI calcite mineral cartridges are designed to fit standard filter housings for ease of compatibility - H-F2520CALCITE is 20" length and fits inside of a 20" Standard filter housings (actual outside dimensions of these housings are approximately 4.5" OD x 22" H).

Features and Benefits of AMI Calcite Filter Cartridges

  • Built-in 100 micron reticulated poly foam pre filter to prevent contamination buildup in the resin bed
  • Built-in 20 micron spun-bonded polypropylene post filter to prevent media fines from being washed out of the filter cartridge
  • Raises pH of water to a non-corrosive equilibrium
  • Reduces Leaching of Metal Plumbing Components and Copper Piping
  • Contains 100% calcite filtration media, a naturally occurring mineral
  • Low uniformity coefficient for maximum contact
  • Slower Reacting for controlled pH correction
  • Standard Cartridge Design Fits Most Standard Residential and Commercial Filter Housings
  • Assembled and Quality Tested in the USA in an ISO 9001-2015 QMS Certified Facility
