2111576 9300149 PCTABS00019 A system for providing an environment of reduced allergen population has base unit (10) that has air inlet (12), filter structure (18), (20) within base unit (10), head unit (36), and conduit structure (34-1), (34-2) communicating between base unit (10) and head unit (36) to form a recirculation path for the air flow. The recirculation path allows a stream of air, from which dust mites, waste and other particulate contaminants have been removed, to flow as a low velocity laminar air flow with a downwardly directed external portion (52) in which a patient's head (particularly its mouth and nose) is adapted to be received.
