Filtrete 20x20x1 Air Filter MERV 11, Allergen Reduction, 4-Pack

The Filtrete Allergen + 2X Dust Defense Filter offers powerful allergen protection and the best dust-busting capacity in our entire collection. This filter captures unwanted allergens and holds twice as much dust as our other home air filters, helping your home become cleaner, fresher, and happier. (Compared to other Filtrete Filters)

The filter holds as much dust as 50 dusting wipes (Dry dusting wipes in normal use conditions), outperforming fiberglass, washable, and non-electrostatic 3-month pleated 1-inch home air filters for your furnace, air conditioner, or HVAC system.

Designed with the exclusive Filtrete Brand 3-in-1 technology from 3M, the filter is engineered to trap unwanted air particles while allowing cleaner air to flow through. It attracts and captures particles such as lint, pollen, dust, pet dander, smoke, and smog.

The Filtrete 1200D MPR has a rating of MERV 11, and the higher the MPR, the more microparticles - such as pollen, pet dander, smoke, bacteria, and viruses - your filter will capture from the air passing through it.

Available in a variety of sizes, including MPR 1000, MPR 1200, and MPR 1550, in 4-inch, 4-inch slim fit, and 5-inch thick air filters, the Filtrete Allergen + 2X Dust Defense Filter is designed to fit your specific needs.

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-inch filters, and at least every 12 months for 4-inch and 5-inch filters. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool, wasting energy. To make the process easier, you can sign up for a filter change reminder program (www.filtrete.com/ChangeReminders) that works for you.

The Filtrete Allergen + 2X Dust Defense Filter is for residential use only.
