12X18X01 Polyester Disposable Filter - Case of 12

Polyester Disposable - Sold 12 to a case

 Disposable panel filters are rigidly constructed using a progressively dense polyester media to maximize dust holding capacity. Two metal grids are thermally bonded to the internal sides of a heavy-duty, one-piece craftboard frame to maintain the media's integrity under adverse operating conditions.
