The inhaled air passes through a filter wad 15 which may be impregnated with liquid inhalant. The exhaled air passes out through a valve 17 comprising a disc having a seating upon an inturned portion 16 of the sleeve 2 and engaging, during exhalation, with inturned portions 19 at the outer ends of a cruciform slot in a cap 18. The whole appliance is formed of material sterilizable by heating, for example aluminium.
