Our AP917HD-S AP904 Water Replacement Filter Compatible with 3M Aqua-Pure Whole House Large Diameter System AP904 with up to 100,000 gallons of filtration capacity. Note: This is not an original 3M product. The brand names and part numbers are for reference only. Elovener is an independent brand.

Our 3-stage filtration system removes 98% of chlorine, sediment, and odor, while the food-grade scale inhibitor prevents limescale buildup in your pipes and appliances – so your clothes stay bright after washing, your hair feels softer after showers, your water tastes clean enough to drink straight from the tap, and your expensive water-using appliances last years longer.

12-Month Long Lifespan for Hassle-Free Maintenance

Each filter provides up to 12 months or 100,000 gallons of clean water for a standard 3-4 person household, 2x longer than most budget whole house filters. For high-use households or areas with extremely hard water, replace every 10 months or when you notice a visible reduction in water flow. No frequent filter changes, no constant monitoring required.

3-step 30-second filter change:

Twist the old filter a quarter turn counterclockwise to remove (no need to shut off your main water line)
Peel the protective seal off your new Elovener filter
Twist the new filter clockwise into the AP904 system until it clicks – done!

Package Includes: 2 x AP904 Water Replacement Filter Cartridges
