Filters are fine BUT STOP SENDING ME MARKETING AND OPINION SURVEY EMAILS. You guys are turning an otherwise pleased customer into one that says bad words when I see your messages in my inbox.Bob Palmer
My first time using a 4" thick filter. 1+ YO Lennox furnace's filter compartment accommodates this size filter, but doesn't guide/hold it flush against air intake. Appears intentional, yet unsure of air purity it puts in the house. I'd give the Company's interaction with customers 4+ stars
Been purchasing 5 furnace filters from tibia Company for several years. This isAn excellent product at a fair price. Weve never had a Problem with the filters
This product has adequate quality. Dont know if it produces the level of filtration indicated by the Merv rating. But all of the suppliers charge too much for this product.
