Description
Add calcium carbonate and raise the pH of acidic or low-mineral RO water
The Omnipure K2548-BB uses calcite—calcium carbonate—as a final-stage mineral medium. When low-pH water contacts calcite, a portion of the media dissolves, adding calcium and alkalinity and helping move acidic water toward a more neutral pH.
What the media contributes to finished RO water
High-purity calcite / calcium carbonate. Calcite dissolves gradually in acidic, low-mineral water, adding calcium and alkalinity. Its neutralizing action naturally slows as water approaches equilibrium.
Useful mineral information without overstating health effects
Calcium is an essential dietary mineral and contributes to normal bone, muscle, and nerve function as part of the overall diet. However, this cartridge does not provide a standardized nutritional dose. The amount added depends on incoming pH, alkalinity, flow, contact time, and media condition.

Installation & maintenance
- ✓Install as the final mineral-treatment stage unless your system layout specifies otherwise
- ✓Use cold, microbiologically safe source water only
- ✓Flush a new cartridge before drinking-water use
- ✓Measure pH or TDS after flushing if a specific finished-water profile is important
Confirm tubing size, flow direction, and desired water profile
For compatible countertop and under-sink RO systems and other point-of-use applications needing calcite remineralization or acidic-water neutralization. Often installed as the final stage.
