This replacement cartridge bundle is an ideal choice for the value conscious consumer. The cartridge should be changed every 6 - 12 months or upon noticeable pressure reduction. To provide prospective to the micron sediment entrapment rating it is important to note the naked human eye can see down to 20 micron and a human hair is 100 microns in diameter. The industry universal dimension of 4.5 inch x 20 inch makes it compatible with 3M AP802 and many other filter housing manufacturers such as Pentek and Culligan. The smaller the micron rating the better the entrapment capability. Shrink Wrapped for Purity.
