Our Recommended AP811-2 Alternative
The Neo-Pure SDG-45-2025 is a great alternative to the AP811-2, since both cartridges share performance and specifications.
The Neo-Pure SDG-45-2025 can be used as a pre-filter cartridge at the point-of-entry before a water softener or UV system. The Neo-Pure SDG-45-2025 utilizes a grooved polypropylene construction to provide a greater surface area, and in turn, a longer filter life and increased capacity for dirt. The porous cylinder inside the filter effectively traps sediment, dirt, and rust without decreasing water flow.
