These filters use mini-pleat glass fiber media with efficiencies from 99.97% (H13) to 99.9995% (U15). All Air Filter Supplies are individually tested to verify that each filter shipped meets the specified efficiency. They are designed for optimize applications, such as health care, commercial, educational and industrial buildings.

The extended media surface combined with precisely controlled bead separator pleating creates low resistance to air flow and save energy consumption. The light weight makes customer easy to install.
