The KW110 filter cartridge is compatible with Whirlpool filter models WHKF-DWH and WHKF-DWHV. Also compatible with Whirlpool WHKF-GD05. The rigid polypropylene filter replacement cartridge closely spun construction effectively removes dirt and sediment with impressive flow rates of up to 8 gallons per minute. Each cartridge contains two distinct micron layers. To provide prospective to the 5 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. 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 raised groove design optimizes the dirt holding capability resulting in longer cartridge life. This replacement cartridge is an ideal choice for the value conscious consumer. The KW110 is shrink wrapped for purity. ProductSiteLaunchDate : 2010-06-22T23:56:12.550Z Size : 1 Count (Pack of 1) SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1 UnspscCode : 40161502
