Abstract: An air cleaning device for removing aerosol particles from an air stream comprising: a particle charger comprising a housing and an electrode arrangement therein for generating air ions in the air stream, the particle charger having a particle charging zone within which, in use, aerosol particles in the air stream are electrically charged via collision with the air ions; a filter for precipitating electrically charged aerosol particles from the air stream moving through the device; and an air mover, comprising a casing, for moving the air stream through the device; wherein the particle charger and the air mover are provided upstream of the filter; and wherein the housing of the particle charger is hermetically sealed to the casing of the air mover in the direction of air flow through the device, such that the particle charger and the air mover are intimately coupled together, whereby all air entering the device has to pass through both the particle charger and the air mover.
