20x25x1 Air Filter, MERV 12, MPR 1500, Allergens, Bacteria & Viruses, 3-Month AC and Furnace Filters, Cleaner Air, Reliable Airflow, 2 HVAC Filters (Actual Size 19.62 x 24.62 x 0.78 in)

#1 Recommended HVAC air filter brand according to the US Brand Health Tracker, Ipsos, June 2022. A higher MPR rating indicates the filter captures more microparticles--like pollen, pet dander, smoke, bacteria and viruses--from the air moving through it. To maintain your heating & cooling or HVAC system's best performance, replace your 1-inch home air filter at least every 90 days, and your 4-inch and 5-inch filters at least every 12 months. A clogged filter reduces airflow and forces the system to work harder to maintain your temperature, using more energy.

Enroll in a filter change reminder service that suits your needs. Compatible with Dash Replenishment; using this feature allows the device sensor to monitor your filter usage and automatically order new filters when replacement is needed. Performs better than fiberglass, washable, and non-electrostatic 3-month pleated 1-inch home air filters for your furnace, air conditioner, or HVAC system. Engineered with exclusive 3-in-1 technology from 3M to capture unwanted airborne particles while allowing cleaner air to pass through
