Abstract

An apparatus for ventilating a bed in a room includes an elongate housing having an upper and lower extent. The upper extent is provided with an air inlet opening for receiving stale air and an outlet duct is provided for exhausting filtered air into the room. A mounting flange extends outwardly from the housing and is received between the bed mattress and boxspring for supporting the housing at the foot of the bed. At least one recirculating duct recirculates filtered air from the elongate housing under the bedcover back to the bed.
