Omnipure K2348-BB Inline Calcite - 6" x 2" Filter

The Omnipure K2348-BB Inline Calcite Filter has been designed to correct pH in filtered water. In recent years there has been all sorts of debates on how to get proper pH balance in drinking water. One of the easiest and affordable techniques is to use a calcite filter. Calcite is a finely crushed and screened white marble, which dissolves into the acidic water, neutralizes the pH, and raises TDS. The K2348-BB is quick and easy to add to an RO system.

  • Calcite adds minerals and TDS back into the water as well as stabilizes the pH level of the water
  • Applications: RO post-filtration, food service, & other POI applications
  • Dimensions: 6" x 2"
  • Connections: 1/4" FPT
  • Capacity: 3 months
  • Filter Media: 100% calcite
