Key Features

• ✅GROOVED SURFACE HOLDS MORE DIRT – The outer wall is square grooved rather than smooth, which adds surface area without tightening the media, so the cartridge loads up with sand and grit before flow starts to fall off. The porosity runs coarse at the outside and progressively finer toward the core, spreading debris through the wall instead of packing it on one face. Rigid construction resists unloading when pressure swings.
• ✅CLEARER WATER FROM EVERY SOURCE – Whether your home runs on municipal tap water or a private well, the cartridge captures the sand, silt, dirt and rust that cloud water and wear out fixtures and appliances. Sediment media works on particles only — for taste and odor add a carbon stage, and for certified contaminant reduction look for cartridges tested to NSF/ANSI standards for those claims.
• ✅EFFICIENCY: Our water filter cartridge eliminates pollutants and impurities from water. At the same time, it effectively preserves many vital minerals. For optimal performance, water filter cartridges should be replaced every 3 to 6 months based on your water quality.
• ✅FEATURES: Our water filter cartridge particularly offers a larger surface area and a longer life. This cartridge eliminates chlorine, bad taste, and odor, and is available in a variety of sizes. This replacement cartridge will provide you with high filtering performance at a lower cost.
• ✅FITS THESE PART NUMBERS – Direct replacement at 5 micron for AP420, sold as 5527407, 55274-07, 5560907 and CFS4201MF, in the AP101T, AP141T and AP100 series housings and most other 10 inch slim line housings. One difference to know: the original AP420 carries a scale inhibitor as well as sediment media. This is a grooved sediment cartridge without that additive, so match the media if scale control is why you bought the original.
• MATCH THE FILTER TO YOUR WATER – Cartridges are maintenance parts, not water treatment plans, and no single one handles everything. Carbon reduces chlorine taste and odor. Sediment media captures sand, silt, dirt and rust. For any specific contaminant you are concerned about, look for a system certified to the NSF/ANSI standard that names it. If you are on a private well, start with a water test.
