20x20x1 AC Furnace Air Filter, MERV 11, Micro Allergen Defense, 6 Pack

Upgrade your central heating and cooling system into a comprehensive home air filtration operation with the Filtrete Allergen Defense Air Filter. This efficient filter is capable of capturing particles of all sizes, ranging from large particles like lint, pollen, dust, and pet dander, to microscopic particles such as smoke and smog. It performs better than fiberglass, washable, and non-electrostatic 3-month pleated 1-inch home air filters for furnaces, air conditioners, and HVAC systems.

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

You can find your preferred size, whether it's MPR 1000, MPR 1200, or MPR 1550, and choose between 4-inch, 4-inch slim-fit, or 5-inch thick air filters. For optimal performance of your heating and cooling system, it is recommended to change your home air filter at least every 90 days for 1-inch filters, and at least every 12 months for 4-inch and 5-inch filters. By ensuring your filter is replaced regularly, you can prevent airflow from slowing down and making the system work harder, thereby saving energy.

If you struggle to remember when to change your filter, you can sign up for a filter change reminder program. Keep in mind that the Filtrete Allergen Defense Air Filter is for residential use only. To simplify the replacement process, you can create a change countdown in the Filtrete Smart app. Simply scan the barcode on your filter's packaging using the app, and select a replacement countdown of 30, 60, or 90 days. When the time is up, you'll receive a notification to change your filter.
