Last 12 I purchased were a hair oversized, causing difficulty replacing. I’m hoping this recent purchase is sized correctly. I replace my filters on the first of every month. So discounts dictate when to purchase.

Excellent quality OEM filters. Perfect fit. I get all my other filters from them as well (refrigerator and pool).

I change the filters in our furnace often, and having a suppy on hand makes that easier. Best thing you can do for your furnace.

Discount Filters always has my 2 filter sizes in Merv 8. Can't say the same for any stores near me, so I could search all day, then still come back here. So I just come to Discount Filters first.
