ABSTRACT:
An air purifying device is provided for removing airborne particles. The device includes a housing including an air inlet and an air outlet. A fan is positioned within the housing for drawing air into the housing through the air inlet and expelling air through the air outlet. A filter assembly is positioned within the housing between the air inlet and the fan. The filter assembly includes a frame and a filter element mounted to the frame. The device also includes a hanger and an elongate hanger support that removably extends within the hanger. Either the hanger or the elongate hanger support is coupled to the frame while the other is coupled to the housing. The hanger can include a channel or a pair of opposed legs configured to form a gap.
