Description
Electrostatic air filters are better at capturing airborne particulates than other types of filters. As air passes over the the polypropylene fibers in electrostatic filters, it causes a static electrical charge around those fibers that attracts and hold particulates until washed off.
These 7/16″ and 1/2″ thick electrostatic filters have 2 inner layers of fine mesh polypropylene netting between 2 outer layers of heavy duty expanded aluminum and are enclosed in a one piece heavy duty aluminum frame.
