The 3M™ Aqua-Pure™ Whole House Standard Diameter Water Filter Drop-in Replacement Cartridge AP420 for the AP100 & standard and large diameter Stainless Steel Housing Series, is a great choice in water filtration. This standard 2.75" diameter drop-in cartridge is manufacturer tested and verified to reduce sediment** down to 5 micron nominal, as well as scale**. Our dual purpose replacement cartridge, the AP420's rigid construction from our proprietary polypropylene manufacturing process, helps to eliminate "unloading" of sediment due to variances in water pressure, sometimes referred to as water hammer. The scale inhibition media helps prevent scale build-up on water heaters (both standard and tankless styles), as well as down-stream plumbing fixtures. Made from FDA (CFR 21) Compliant Materials. 2 Pack of Filters.
