Five 4.5 inch x 20 inch water filter alternative cartridges. The rigid polypropylene construction effectively removes dirt and sediment with impressive flow rates of up to 40 gallons per minute. Each cartridge contains two distinct micron layers. Larger particles are trapped near the exterior and progressively finer particles towards the filter core. Thus the cartridge has exceptional solids-holding capacity and will perform longer. The KW811-2 features a raised ridge grooved design which provides a significant increase in surface area. Please note these cartridges do not have the decorative end caps. These end caps are not necessary. Internally the water filter housing is equipped with an upper and lower protrusion that cuts a ring into the polypropylene cartridge thereby creating a positive seal.
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. 20 Micron gradient density melt blown polypropylene construction. To provide prospective to the 20 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.
