I replace the furnace and air conditioner filters each year.

I use only 3m filters when I change the filters in my air conditioner and furnace. The 3m filters in my furnace get changed 2 times each year to keep our air cleaner. Our allergies seem to have been better since I have been keeping up with changing the 3m furnace filters. Also once a year I change the 3m air conditioner filters. I only do the 3m air conditioner filters once a year as we only use the air f or 1 season a year and not even everyday. Our doctor was the one who suggested using only 3m filters as they will also help reduce the allergens in the air.
