AP810 / WHKF-GD25BB Generic Water Filter Cartridge Alternative by KleenWater

3M Aqua-Pure 4.5 inch x 10 inch AP801 generic water filter cartridge alternative. Sales reference #99663311. This water filter replacement cartridge is a high quality, low cost alternative to the AP810. The rigid poly-spun construction effectively removes dirt and sediment with impressive flow rates of up to 20 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 PWF810 features a raised ridge grooved design which provides a significant increase in surface area. This replacement cartridge is an ideal choice for the value conscious consumer. Its performance is commensurate to the competition at a fraction of the cost. 5 Micron Gradient Density :: Melt Blown Polypropylene Construction :: Shrink Wrapped for Purity :: Flow Rate 20 GPM :: Recommended Cartridge Change Every 6 Months or Upon Substanstial Pressure Reduction. The industry universal dimension of 4.5 inch x 10 inch makes it compatible with filter housing manufacturers such as GE, Culligan, Cuno, Omni, Kenmore, Whirlpool and Ametek, among others. The smaller the micron rating the better the entrapment capability.
