The Pentair OMNIFilter Easy Flow US1 replacement cartridge keeps fresher, better-tasting water flowing through the Easy Flow US1 undersink filtration system. It reduces chlorine taste and odor for cleaner-tasting water straight from the tap, and is NSF/ANSI Standard 42 certified for the reduction of substances specified on its performance data sheet.

Its quick-change, click-in design makes filter replacement effortless: simply flip the filter cover open, pull out the old filter, click the new one in with the triangle on the label aligned to the diamond on the cover, and snap the cover closed - no tools and no water shutoff required, thanks to the system's integrated check valves.
