(FR) FILTRE A AIR PERMANENT EXTREMEMENT EFFICACE
Abstract: front page image
(EN)An air filter for use in residential and commercial heating and air conditioning systems including a laminated unit (100) having a filter media (102) where either side of the filter media (102) has a porous layer (104, 106) of passive electrostatic netting. The air filter has a corrugation configuration (142, 144) to increase the available surface area when compared to conventional flat filters.
