20x30x1 Air Filter, MERV 11, MPR 1000, Micro Allergen Defense, 6 Pack

Upgrade your central heating and cooling system with a Filtrete Allergen Defense Air Filter and turn it into a comprehensive whole-home air filtration system. This efficient filter is designed to capture particles of various sizes, ranging from larger particles like lint, pollen, dust, and pet dander to microscopic ones like smoke and smog. It outperforms fiberglass, washable, and non-electrostatic 3-month pleated 1 in. home air filters for furnaces, air conditioners, or HVAC systems.

The filter is equipped with exclusive Filtrete Brand 3-in-1 technology from 3M, which effectively traps unwanted air particles while allowing cleaner air to flow through. It has the ability to attract and capture particles such as lint, pollen, dust, pet dander, smoke, and smog, and is rated at 1000 MPR with a MERV 11 rating.

The MPR rating indicates the filter's capability to capture microparticles such as pollen, pet dander, smoke, bacteria, and viruses from the air passing through it. Sizes available include 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 can slow down air flow and make the system work harder, leading to wasted energy. Consider signing up for a filter change reminder program to avoid this. Keep in mind that the filter is for residential use only.

You can also create a change countdown in the Filtrete Smart app. Simply scan the barcode on your filter’s packaging using the app, then choose 30, 60, or 90 days for your replacement countdown. When the filter lifespan is up, you’ll receive a notification to change your filter.
