Made from high-integrity, high-loft polyester media that resists moisture, will not sag, and is durable, these filters are suitable for use as prefilters, primary filters, second-stage filters and paint spray booth final filters. Media has low resistance and is coated with a non-drying adhesive for optimum particle collection without sloughing. Internal wire frame is self-gasketing and self-sealing to prevent leaks and bypass. Cube and multi-pocket filters have high surface area and exceptional dust-holding capacity. They maintain their shape in all airflow conditions and are easy to install - no clips or latches are required.
