Filters were received in just a few days. Have not had a chance to use . Furnace and A.C. are brand new. Still using filters installed with purchase. Anxious to see difference when Filterbuy's are used.
I haven't even used mine yet but am impressed with the company for making them in America, and not charging me when I made the mistake of entering the wrong size! It'll be nice to have a reliable company to get good quality air filters from now that I know about you guys.
