The 3M Filtrete MPR 1550 MERV 12 air filter is a deep pleat furnace filter designed to create a cleaner, healthier home environment by capturing unwanted particles from household air. This 4-inch thick filter measures 16x25x4 inches and comes in a convenient 2-pack.

The filter features exclusive Filtrete 3-in-1 Technology that pulls in and traps unwanted particles while allowing cleaner air to flow through. It captures up to 50% of small airborne particles including viruses, bacteria, pet dander, and smoke, as well as larger particles like lint, pollen, and household dust. The electrostatically charged design attracts and traps more particles with each cycle through your heating and cooling system.

This furnace filter is Certified Asthma and Allergy-Friendly and has been verified to contain at least 50% recycled content by GreenCircle Certified. It is EPA registered and backed by North America's most trusted brand of HVAC filters. The filter should be changed at least every 12 months for optimal performance, and the Filtrete Smart App can help set customized change reminders based on your home environment.
