[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - in effect filter] electrostatic filter FFU for some reason, fibers and particles can take charge, electrostatic effects. Filter material with electrostatic filter effects can be significantly improved. Reason: electrostatic dust make change trajectory and hit the obstacle, electrostatic dust so sticky on the media more firmly. Material long-term static electricity is also referred to as "electret" materials. After the same material with a static resistance, the filtering effect will be significantly improved. In the filtering effect of static electricity can not afford a decisive role HEPA, only play a supporting role.
