Frequently asked questions
Electrostatic media has a significantly lower resistance than traditional medias, which means you don’t need to use as much filter material, so they are lighter and more energy efficient. This is achieved by using a more open or porous media, one that uses electrostatic charge to enhance the single-pass efficiency, without clogging. By charging the electrostatic filter, particulates are pulled towards the media threads and stick to them like magnets.
