  • Patent number: 7235120
    Abstract: A battery (16) drives an electric motor (17) which in turn drives a fan (18). A circuit board (20) controls the operation of the motor and fan to maintain the flow rate. Air is drawn through an inlet (22) and out through a vent (24). Foam discs (32) and (34) may extract particles from the air and an electrostatic filter may attract aerosols in the air.
