14x20x1 MERV 11 Air Filter, Micro Allergen Defense, 6 Pack

Enhance your central heating and cooling system with a Filtrete Allergen Defense Air Filter and turn it into a comprehensive home air filtration system. This efficient filter is capable of capturing a wide range of particles, from larger ones like lint, pollen, dust, and pet dander to microscopic ones such as smoke and smog. Unlike fiberglass, washable, and non-electrostatic filters, this 3-month pleated 1 in. home air filter for furnaces, air conditioners, or HVAC systems outperforms them all.

It is designed with the exclusive Filtrete Brand 3-in-1 technology from 3M to trap unwanted air particles while allowing cleaner air to flow through. The filter attracts and captures particles like lint, pollen, dust, pet dander, smoke, and smog, and has a 1000 MPR rating of MERV 11. The higher the MPR, the more microparticles it will capture from the air passing through it, including pollen, pet dander, smoke, bacteria, and viruses.

Various sizes are available, including MPR 1000, MPR 1200, and MPR 1550 in 4 in., 4 in. slim fit, and 5 in. thick air filters. 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 will slow down air flow and cause the system to work harder, leading to energy wastage.

Remember to sign up for a filter change reminder program to ensure timely replacements. This product is for residential use only. Use the Filtrete Smart app to create a change countdown. Simply scan the barcode on your filter’s packaging with the app and choose 30, 60, or 90 days for your replacement countdown. When the lifespan is up, you’ll receive a notification prompting you to change your filter.
