The 3M Aqua-Pure AP117 whole house water filter features a 5-micron nominal rating, effectively reducing sediment, dirt, sand, rust, and silt from your home's water supply. This cartridge has a filtration capacity of up to 20,000 gallons or 12 months of service life, whichever comes first. Its high-capacity design makes it ideal for standard whole house applications, providing reliable sediment reduction for all water entering your home.

The AP117 cartridge is specifically designed to fit the 3M Aqua-Pure AP11T and AP101T whole house filter housings. It measures approximately 9-7/8" in length with a standard fit, making it a direct drop-in replacement. For best performance and leak-free operation, always pair the AP117 with its compatible Aqua-Pure housing rather than generic alternatives.

3M recommends replacing the AP117 cartridge every 12 months or after 20,000 gallons of filtered water, whichever occurs first. However, if you notice a drop in water pressure or visible sediment buildup, earlier replacement may be necessary—especially in homes with heavily sedimented or well water. Regular replacement ensures optimal flow rate and continued sediment reduction throughout your plumbing system.

The AP117 is engineered as a dedicated sediment reduction filter. It captures rust particles, sand, silt, dirt, and scale from incoming municipal or well water, helping protect your plumbing, water heater, appliances, and downstream filtration systems from sediment damage. Please note the AP117 is not designed to reduce chlorine, taste, odor, or chemical contaminants—for those, consider pairing it with a carbon-based post-filter.

The 3M Aqua-Pure AP117 is manufactured to meet 3M's rigorous quality standards and is designed with materials that comply with NSF/ANSI Standard 42 guidelines for material safety. It supports a robust service flow rate of up to 20 GPM (gallons per minute) with a maximum operating pressure of 125 psi and a temperature range of 40°F to 100°F, making it suitable for whole house installations without compromising household water pressure.
