The Aqua-Pure AP420 Ships As A 2-Pack!
The Aqua-Pure AP420 is a multi-purpose replacement cartridge designed for standard and large diameter stainless steel Aqua-Pure housings. This drop-in cartridge has been tested and verified to reduce sediment as small as 5 micron nominal, as well as reduce hard-water scale. The reduction of scale protects water heaters, pipes and appliances.

The AP420's rigid polypropylene helps eliminate sediment "unloading" due to variances in water pressure, while the filters ribbed surface is designed to increase the filters surface area.
