The Best Furnace Filters

I teamed up with 3M to make the best furnace filter on the market : Filtrete air filters. These filters catch 99.9% of contaminants in the air– mold, bacteria, pet dander, dust mites, and other allergens– so you and your kids are not cleaning the air with your lungs. They also allow better air movement to help your furnace and ventilation work better. Can you change your filter too often? The answer is no. Too many people don’t even realize that your need to change or check the furnace filter. A rule of thumb is to change the filter at least every three months. If I were you, I ‘d change it once a month because I’d rather have the filter clean the air than have my family’s lungs doing the job.
