Filtrete 20x25x1 AC Furnace Air Filter, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 6 Pack

Opt for a Filtrete Allergen Defense Air Filter to transform your central heating and cooling system into a whole-home air filtration operation. This no-nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog). Designed with exclusive Filtrete Brand 3-in-1 technology from 3M, it is engineered to trap unwanted air particles while allowing cleaner air to flow through.

The Filtrete Allergen Defense Air Filter outperforms fiberglass, washable and non-electrostatic 3-month pleated 1 in. home air filters for your furnace, air conditioner or HVAC system. With a MERV 11 rating and an MPR (Microparticle Performance Rating) of 1000, this filter effectively attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog.

The higher the MPR, the more microparticles, including pollen, pet dander, smoke, bacteria and viruses, the filter will capture from the air passing through it. Filtrete offers a range of MPR ratings, including 1000, 1200 and 1550, available in 4 in., 4 in. slim fit and 5 in. thick air filters, ensuring you can find the perfect size for your system.

For optimal performance of your heating & cooling system or HVAC system, it is recommended to change your home air filter at least every 90 days for 1 in. filters, and at least every 12 months for 4 in. and 5 in. filters. A dirty filter can slow down air flow and make the system work harder to keep you warm or cool, wasting energy.

To make the filter change process more convenient, Filtrete offers a Smart app that allows you to create a change countdown. Simply use the app to scan the barcode on your filter's packaging, then choose 30, 60 or 90 days for your replacement countdown. When the lifespan is up, you'll receive a notification to change your filter.

Filtrete Allergen Defense Air Filters are designed for residential use only. By incorporating this high-performance filter into your HVAC system, you can transform your home into a cleaner, healthier environment, while also improving the efficiency of your heating and cooling system.
