Pro-tech Filters is the one-stop shop for standard and hard to find air filters. We carry all the standard sizes for your air conditioner or furnace unit in both the industry standard Eco-Aire branded filters and the premium 3M Filtrete Pro Series. The Pro Series was developed by Filtrete to perform to the same standards as the 3M Filtrete Allergen filters sold in stores everywhere but they have MERV rated them for the HVAC contractor. What does this mean to you? You can now get standard Eco-Aire filters and 3M Filtrete filters in ALL Sizes as well as in any custom or odd configuration.

Here at Pro-Tech Filters we offer a full line of Eco-Aire and 3M Filtrete residential and commercial air filters and accessories in standard and hard-to-find custom sizes. Eco-Aire filters come in a variety of sizes and are available in 1", 2", 3", 4", 5" and 6" depths with the 3M coming in 1" and 4" depths.. In addition, the Eco-Aire and 3M Filtrete filters can be custom made to your exact size. Eco-Aire filters are comparable to the same-sized Accumulair, American Air, Flanders Precisionaire and Naturalaire air filters at a fraction of the cost without losing any quality and the 3M Filtrete are the premium filter for allergy sufferers and those wishing to eliminate air borne particles without slowing their air flow.
