The 30/30® is a high-efficiency panel filter designed as a strong, value-added upgrade from ordinary MERV 8s, says the company. It has a very low initial resistance, and a low maintained resistance, to airflow. The design of the filter, with its radial pleat design, allows full use of the media for maximum dust-holding capacity. The media for the filter is “all-mechanical,” rather than electrostatic, and maintains consistent, high-removal efficiency throughout the filter’s life. The radial media pleats on the 30/30 are secured by a welded wire grid, spot-welded on 1-inch centers. The grid is treated for corrosion protection and is bonded to the media to prevent oscillation. The MERV 8 30/30 is rated for low flammability by Underwriters Laboratories as Class 2, and is available in 2- and 4-inch configurations suitable for both residential and commercial use.
