Glasfloss Z-Line series air conditioning filters and oven filters are of the type of pleated medium with an extended surface. The medium used is composed of 100% synthetic fibers, which were first introduced in 1950 by Pittsburgh Plate Glass (PPG) through a patented Modigliani process. This process revolutionized the industry, allowing for the production of custom-designed filters for air conditioning systems. Air Duct began manufacturing special-sized filters for them and other contractors in the New York area to meet this need.
Because Owens Corning didn't sell its filter media in bulk, the filters were first manufactured by dismantling standard filters, cutting media and screens, and manufacturing new frames to specifications. They became the first authorized independent manufacturers of “Dustop” air filters in the United States. Contractors with special filter orders couldn't receive a quick delivery and sometimes had to operate systems without filters. As the air conditioning industry expanded, the need for original and replacement special-size filters grew rapidly.
Filter Systems maintains one of the largest warehouses and filter inventories in the DFW area with more than 25,000 square feet of floor space and an average of more than 50,000 floor filters at any given time. Glasfloss produces a complete line of air filter products in Dallas, starting with disposable fiberglass filters, pleated filters, bag filters, automatic roll filters, rigid cells and HEPA, as well as many other types. A turnkey filter service is also provided if necessary, including a filter study, automatic programming and reliable professional technicians. It's clear that Glasfloss air conditioning filters are well above average in both performance and price; however, for people with respiratory problems or those who live in areas with poor air quality, this high performance certainly pays off.
