Air filters reduce household dust, pollen, mold spores, and pet dander from the air in your home. To improve your home's air quality, extend the life of your furnace, and keep your energy bills low, you should check your air filter every month-and change it at least every three months.

Replace your furnace filters now and get a head start in the fight against ragweed, mold, and dust mites!

Not sure which filter to choose? Consider the degree of air filtration you require for your family's health and comfort. A filter with a lower Microparticle Performance Rating, or MPR, will filter pollen, mold spores, dust, and dust mite spores, while a filter with a higher MPR can filter pet dander, viruses, smoke, and household odors.
