    When it comes to your furnace, you should know that your filters are pretty important and shouldn't ever be ignored or forgotten. After all, it's the filters that remove the allergens and pollutants from the air that you breathe. With a MERV 11 rating, these filters will remove over 95 percent of all particles larger than 1 to 3 microns. That's pet dander, pollen, mold spores, dust mites, and more. You should make sure to inspect your filters monthly and replace them every three months for maximum efficiency.
