Great selection of filters. So glad they have filters of all sizes, could not find these (18x20x4) in store. Website was easy to order from. Order arrived on time and undamaged. Great service and filters are of great quality!

Furnace filters

My size needed is a difficult size to find(18X20X4). They not only had the size I needed but with different levels of allergen control and bulk packs. Shipping was very quick. Price was little steep but like I said, hard to find so didn't have much choice...
