Disposable Pre-Filter is manufactured using high quality synthetic media blend which provides medium ASHRAE performance and high dust loading capacity. The frame is made from two mating pieces of die cut fiber board bonded together to form a solid, double wall around the entire outer edge of the filter.
The media pack is bonded to the die cut frame at all points of contact – around the edges of the pleat pack and at each point where the pleat tips touch the die cut support members on both sides.
