The Aqua-Pure AP810-2 features a 5-micron nominal rating, effectively reducing sediment, dirt, sand, rust, and silt from your entire home's water supply. Each cartridge has a filtration capacity of up to 100,000 gallons or 12 months of service life, whichever comes first. Its high-capacity design makes it ideal for large households, point-of-entry applications, and homes on well or municipal water systems requiring robust sediment removal.

Yes, the Aqua-Pure AP810-2 is tested and certified against NSF/ANSI Standard 42 for material safety and structural integrity. It is specifically engineered to fit the Aqua-Pure AP11T and AP12T whole house filter housings (also compatible with the AP810 cartridge specification). The cartridge measures approximately 9.75" x 4.5" (Big Blue standard size) and features a built-in gasket to ensure a leak-free seal inside the AP800 series housing.

The AP810-2 is a dedicated sediment reduction cartridge that targets dirt, sand, silt, rust particles, and scale particulates down to 5 microns. It is constructed from a grooved polypropylene media that traps particles throughout the depth of the filter, extending life and maintaining flow rates up to 20 GPM. Note: this cartridge is designed for particulate filtration only—it does not reduce chlorine taste or odor. For chlorine reduction, pair it with an Aqua-Pure carbon cartridge downstream.

3M Aqua-Pure recommends replacing the AP810-2 cartridge every 12 months or after 100,000 gallons of usage, whichever comes first. However, homes with heavy sediment loads, well water, or high daily water consumption may need replacement sooner. A noticeable drop in water pressure throughout the house is the primary indicator that the AP810-2 has reached capacity and needs to be changed to restore optimal flow.

Installation is straightforward: shut off the main water supply, relieve pressure by opening a downstream faucet, and use the housing wrench to unscrew the AP11T or AP12T sump. Remove the old cartridge, clean the housing interior, and insert the new AP810-2 with the gasket end facing up to seal against the housing cap. Lubricate the sump O-ring with food-grade silicone, hand-tighten the sump, then slowly restore water supply and flush the system for 5 minutes to remove any loose carbon fines or trapped air before use.
