3M Aqua-Pure Whole House Water Filter System AP904

This whole house water filter system protects your pipes and appliances while providing great-tasting drinking water throughout your home. The AP904 reduces sediment, chlorine taste and odor, and scale, improving water quality and taste. Installed as a point-of-entry (POE) system, it helps protect plumbing and fixtures. Maintenance is simple with a quick quarter-turn cartridge replacement. The scale inhibition feature uses polyphosphates to prevent mineral buildup. It features 1" stainless steel inlet/outlet connections for peak flow rates up to 20 gpm and an innovative Sanitary Quick Change (SQC) design for easy cartridge changes without needing a wrench. The 304 stainless steel head assembly is corrosion-resistant for long service life. Tested and verified by manufacturer's laboratory. Replace every 12 months or 100,000 gallons.
