K2548 Calcite Remineralization Filter
10" x 2" inline calcite filter that neutralizes acidic water and raises pH to reduce corrosion downstream
The Omnipure K2548 uses crushed and screened calcite (white marble media) to neutralize acidic or low pH water, producing a less corrosive effluent that protects your plumbing and fixtures. This 10" x 2" inline filter installs directly to your water line with minimal risk of leaks, and is available with 1/4" or 3/8" fittings in both FPT and quick connect configurations.
Why the K2548 Matters for Acidic Water
pH Correction
Calcite media naturally raises pH by dissolving calcium carbonate into water, neutralizing acidity and preventing corrosion of pipes and fixtures
Inline Installation
K series design installs directly into your water line with minimal footprint, reducing weeping or seepage common with other filter housings
Fitting Flexibility
Available in BB (1/4" FPT), CC (3/8" FPT), JJ (1/4" QC), and KK (3/8" QC) to match your existing tubing and connections
6-12 Month Service
Replace every 6 to 12 months depending on water chemistry and flow rate to maintain effective pH correction
Natural Calcite Media
Crushed and screened white marble provides consistent, food-grade calcium carbonate for safe pH adjustment without chemicals
Post-RO Application
Ideal for remineralizing reverse osmosis water, which is often slightly acidic after permeate production
Where to Use the K2548
The Omnipure K2548 is designed for reverse osmosis systems, point-of-use drinking water lines, and any application requiring pH correction or remineralization. Common uses include post-RO remineralization, well water pH adjustment, and specialty beverage or aquarium applications. Verify your tubing size before ordering: 1/4" and 3/8" refer to the outside diameter (OD) of tubing, not NPT thread size. Note that NPT fittings measure larger than their nominal size on a ruler—refer to the sizing chart to avoid confusion.
Omnipure has been manufacturing reliable inline filters for decades, trusted by water treatment professionals and homeowners alike.
