Extended-Surface Air Filters

The 3D basket filters extend either inside or outside an enclosure, doubling surface area. Housed in a one-piece fabricated frame, the filters come in hexagon, square, rectangular, and diamond-grid patterns for 85% openness. A variety of foam media options provide high dust arrestance and lower resistance where permanent, cleanable filters are needed.
