AP810 is a 4. 5" diameter drop-in cartridge that is manufacturer tested and verified to reduce sediment down to 5 micron nominal for cleaner drinking water. Rigid polypropylene fiber construction, which helps capture and retain sediment from your water and prevent particle release that can result from system flow upsets. The grooved surface increases total surface area for longer cartridge life as compared to 3M non-grooved surface cartridges. * With these features, the AP810 is a great choice in water filtration and is ideal for larger homes with at least 2. 5 bathrooms. *To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the cartridge every 6 months or sooner if a reduction in water flow occurs is required. Filter life is dependent on actual use and incoming water quality.
