This effective filter is capable of capturing particles of various sizes, from large ones like lint, pollen, dust, and pet dander, to microscopic ones like smoke and smog. The actual filter size is 15.88 in x 24.56 in x 4.31 in. It is designed to be compatible with Honeywell furnaces that require a 4 filter.

Filtrete Brand is the most recommended brand of HVAC Air Filters, according to the US Filtrete Brand Health Tracker, Ipsos, June 2022. A higher MPR rating means that the filter can capture more microparticles such as pollen, pet dander, smoke, bacteria, and viruses from the air passing through it. For optimal performance of your heating and cooling system or HVAC system, it is recommended to change your home air filter at least every 12 months for 4 in.

A dirty filter will slow down air flow and cause the system to work harder, wasting energy to keep you warm or cool. To avoid this, sign up for a filter change reminder program. The Filtrete Allergen Defense Air Filter captures more particles compared to fiberglass air filters, including lint, pollen, dust, pet dander, smoke, and smog. The MPR 1000 has a rating of MERV 11.

Using the Filtrete Smart App, you can create a change countdown by scanning the barcode on your filter’s packaging. Then, simply choose 3, 6, or 12 months for your replacement countdown. Once the lifespan is up, you’ll receive a notification reminding you to change your filter.
