Aqua-Pure™ AP420 Water Filter – Two 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 Aqua-Pure™ 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.

Our recommended replacement for the discontinued CFS4201MF filter.

Product Benefits:

• Technology provides fine sediment filtration down to 5 micron
• Rigid construction helps to eliminate sediment “unloading” due to variances in water pressure
• Double open ended design allows for filtration regardless of which way it is installed in housing
• Scale Inhibition drop-in cartridge helps prevent scale build-up on water heaters (both standard and tankless styles), as well as down-stream plumbing fixtures
• Gaskets on both top and bottom help provide sealing in any housing, helping to prevent bypass of unfiltered water down-stream
