Inside of or adjacent to one end or other wall of a dwelling room or the like there is provided an air-pervious "false" wall spaced in advance of the true wall thereof, thereby defining therebetween a plenum space. Throughout a substantial portion of its extent the false wall comprises a readily air-pervious fabrication, such as for example an extremely loosely woven fabric of natural or synthetic fibers or wire strands or the like; or a parallel strand curtain; or some other highly perforate fabrication such as a punched sheet member or the like. In any case the false wall is preferably decoratively equivalent to the viewed surface of a conventionally decorated room wall. Supply air inlet means are provided in one-way open system communication with the plenum space; the air supply thereto being beneficiated/"conditioned" (heated, cooled, humidified, dehumidified, filtered, etc.) either externally of or within the plenum space. The invention features provision within a plenum space as aforesaid a positive air displacement/transport device which only leisurely moves the beneficiated air through the false wall and thence through the dwelling spaced towards an outlet remote from the false wall. Because of its air-pervious nature the false wall "breathes" a room-wide diffused supply of suitably beneficiated air into and through the room for temperature/humidity/filter control thereof; silently, and without perceptible draft effects.
