Initial efficiency filter

Initial efficiency filters are designed for the primary filtration of air conditioning systems, mainly used for filtering dust particles larger than 5μm. They come in three styles: plate-type, pleated, and bag-type. The frames are available in paper, aluminum, and galvanized iron, with filtration materials including non-woven fabric, nylon mesh, activated carbon filter media, and metal mesh. The protective meshes are double-coated plastic wire mesh and double-coated galvanized wire mesh.
