3M™ Aqua-Pure® AP800 Series Whole House Filter Drop-In Cartridge AP811-2

New, improved carbon based drop-in formulation features a grooved cartridge to increase surface area for a longer cartridge life. Rigid construction helps to reduce sediment "unloading" due to variances in water pressure and provides fine sediment filtration down. Both ends contain Santoprene® gaskets to help provide sealing within housings to help prevent bypass of unfiltered water and contaminants. Materials are FDA CFR-21 compliant.
