One of the many air filters in my home is a 10x10x1 which is an unusual size. Im looking for a non pleated cheap fiberglass filter which lowes, depot and WM no longer carry. I have put in a couple orders from online retailers but have recently canceled because of being on back order until june. Does anyone know an online retailer that I can purchase a case or two? Most places want to sell you filters that cost 5-15 dollars each and these small cheap ones should be no more that 2 bucks each.
