The 3M Filtrete MPR 2500 Premium Allergen & Ultrafine Particles Air Filter is a high-performance HVAC filter designed to help capture unwanted particles from your household air, contributing to a cleaner, fresher home environment. This 20x30x1 inch pleated filter comes in a convenient 4-pack.

With a 2500 MPR and MERV 14 rating, this filter achieves a 77% small particle capture rate, helping to trap countless microparticles such as pet dander, smoke, bacteria, and up to 90% of virus airborne particles. The exclusive Filtrete 3-in-1 technology pulls in and traps unwanted particles while allowing cleaner air to flow through. The filter also captures larger particles including lint, pollen, household dust, mold spores, and dust mite debris.

The electrostatic pleated design uses polypropylene material for effective filtration. Each filter lasts up to 3 months and should be changed regularly for optimal performance of your furnace, air conditioner, or HVAC system. The Filtrete Smart App (iOS or Android) allows you to set 30-, 60-, or 90-day reminders to change your filter. Filtrete is North America's most trusted brand of HVAC filters and this product is Certified Asthma & Allergy Friendly.
