This polyester disposable filter is an improved version of the traditional fiberglass furnace filter which was invented at about the same time as air conditioning. The polyester media in this filter increases the efficiency and lowers the air resistance over the popular fiberglass filter. We selected this Glasfloss brand filter for it's strength and durability.
Product Rating: (2.5 of 6 STARS) This is an improvement on the traditional fiberglass disposable furnace filter that has been used by homeowners for more than 50 years. There are literally millions of these in service. Among polyester disposable filters, this is by far the best brand we have seen. Although it is an economical filter solution, it is not one of the flimsy models you would likely find at a large chain or discount store. This Glasfloss brand product is of the highest quality construction. We gave it a rating of 2.5 out of 6 Stars because it is at the upper limit of the low-end filter options.

Product Description: Features The Glasfloss Polyester Disposable Panel filter is a step up from the fiberglass disposable filter that has set the industry standard for more than 50 years. This rigidly constructed filter maintains its integrity where others fall short. Always the highest quality, Glasfloss Disposable Panel filters have metal grids on both the air entering and air leaving sides.
Construction The Glasfloss Polyester Disposable Panel filter now uses "Polystrand" polyester encapsulated filter media to maximize its high dust holding capacity and lower air flow resistance over traditional polyester media filters. The media is held between two metal grids to prevent filter blow-out under normal operating conditions. The metal grids are thermally bonded to the internal side of a heavy-duty one-piece kraft fiberboard frame. This closed corner construction prevents dust laden air from by-passing the media through open corners. The filter frame is clearly marked with size, UL classification, and air flow direction.
Rated UL Class II.
