Aqua-Pure AP810-2: Whole House Replacement Filter Cartridge for AP802 – Large Capacity

Overview

The Aqua-Pure AP810-2 is a large-capacity, drop-in replacement cartridge designed for use with AP802 whole-house housings. It targets sediment and rust particles to help deliver clearer water throughout the home, from the kitchen faucet to the shower.

This 4.5" diameter, 20" long cartridge features a rigid polypropylene fiber construction and a grooved surface. The grooved design increases total surface area, supporting longer cartridge life and steadier filtration under varying flow conditions.

What it filters and how it performs

The AP810-2 reduces sediment down to 5 microns nominal and helps capture rust particles, contributing to clearer water across everyday household uses. 3M’s Micro-Klean XL progressive porosity technology guides water through progressively tighter pores, balancing filtration with a strong, reliable flow.

• Operational range: 40–100°F (4.4–37.8°C) and 25–100 psi
