A furnace filter purpose is to help keep your furnace clean, not your home. Filter manufacturers do an excellent job marketing filters that clean your air, the only thing they do is restrict the air flow throughout your home and stress out your furnace and a/c. There are some excellent air filters on the market that are separate from your furnace, you can also install a UV lite in your furnace that kills mold spores. After all this spending on air quality remember that the clean air is outside, the answer is to exchange the air in your home. Check out the EPA’s website. Just buy the cheap $1.00 filters and at a minimum change every three months but I recommend every month.

Thanks, Tim
