An air treatment device is adapted to be mounted on and directly supported by an electrical socket. A treatment medium, such as a replaceable electrostatic filter or a replaceable absorber/adsorber, is located at the front of the device. A fan draws air through the medium and particles with a particle size above 0.1 .mu.m are removed.

1. An air treatment device adapted and dimensioned to be plugged directly into an electrical mains socket, which comprisesa housing dimensioned to be between 5 cm and 15 cm across a face of the device opposed to the face of the device intended to be adjacent the socket, said housing containing: an air treatment medium, a reverse-curve impeller fan adapted to cause air to flow through the treatment medium, said fan having from 6 to 12 blades and an axial thickness between 1 cm and 5 cm, whose radially outer ends are spaced away from the housing so as to provide a clearance of from 1 mm to 20 mm, a motor to drive the fan at less than 3,000 revolutions per minute, and means for transforming alternating current from the mains socket to direct current for operating the motor, and a plurality of pins projecting outwardly from the housing and adapted to fit within the socket to supply electricity to the motor, wherein the fan includes an integral hub adapted to accommodate the motor within the hub and to facilitate support of the device in the electrical socket, andwherein the device is supported solely by the fitting of the pins within the electrical socket.
