upon collection until initiation of filtration thereof, said
housing hand movable while in operation within a space to a point
source site within said space where pollution is originating, and
having at least one flexible, extendably maneuverable airborne-
pollutant collector member having at least one articulatable
exterior support structure and a distal end positionable at a
point source site of pollutant origin;
b) a vacuum system within the mobile housing in
communication with the at least one collector member to draw
airborne pollutants into the mobile housing through said
collector member and to a filter system; and
c) a filter system comprising a plurality of removable
