Patent attributes
An air filtration device for suppressing biological pollutants for closed environments, including at least one enclosure with at least one air inlet, at which at least one perforated conducting grille is located, that has a present negative electrical potential adapted to emit electrons when air flows, so as to give negative electric charge to particles to which microorganisms adhere, at least one air passage duct being formed between at least one plate having predefined positive potential for collecting negatively charged particles to which microorganisms adhere, at least one deflector plate having a negative potential adapted to divert the particles to which microorganisms adhere, an electrical field being generated between the collector plate and the deflector plate, facing each other, the field to divert and precipitate the particles to which the microorganism adhere onto the collector plate, and an inactivator for inactivation of the microorganisms provided and at least one filtered air outlet.
