The air cleaning system, located e.g. in the roof space of a dwelling, consists of a suction apparatus (12) that draws in external air through a duct (8), filters (9) and a heater or cooler (10), delivering the treated air to the various parts of the building through conduits (17) and outlets (13). The apparatus (12) is set so that there is sufficient air to force it out of the building through ventilation grilles (4), creating an external barrier (15) to dust (2) and pollutants (11). It can be controlled manually or automatically, and the filters have a detector (19) to warn when they are blocked. |
