COMPATIBILITY & APPLICATIONS

Where This Filter Belongs

The K5553 is designed for residential and light commercial applications where nitrate contamination is present, typically in agricultural regions or areas with well water impacted by fertilizer runoff. It integrates into reverse osmosis systems as a pre- or post-filter, or can be used as a standalone inline cartridge in dedicated nitrate reduction systems. Multiple fitting configurations (Quick Connect and NPT) make installation straightforward across different plumbing setups. Note that NPT fittings measure larger than their nominal size—a 1/4" NPT actually measures approximately 0.540" in diameter. This filter is part of Omnipure's K-Series specialty line and should be replaced when nitrate breakthrough occurs or according to water testing results.

💧 Nitrate filters require monitoring. Test your water regularly to confirm the resin is still active—once nitrate levels start rising in your filtered water, it's time to replace the cartridge regardless of flow rate.
