The Aqua-Pure AP811 replacement cartridge is a large-diameter cartridge ideal for larger homes and commercial applications. Although the AP811 is compatible with most conventional Aqua-Pure™ housings and whole house water filtration systems, it has been specifically designed to work with the following whole house systems: AP801 (discontinued), , , , AP801T-C, and AP801-1.5-C.

The AP811 cartridge efficiently removes particulate impurities and contaminants from drinking water. It uses an innovative, patent-pending technology that provides a very fine filtration system, down to 25 microns. The cartridge's grooved design increases surface area for a longer filter lifespan, while the rigid construction helps to eliminate sediment "unloading" due to variances in water pressure. This design provides a 25% longer filter life when compared to similar looking water filter replacements.

Product Benefits:

• Patent pending technology provides fine sediment filtration down to 5 micron
• Grooved cartridge increases surface area for longer cartridge life
• Rigid construction helps to eliminate sediment “unloading” due to variances in water pressure
• Ideal for larger (2.5 baths) homes and commercial applications
