ABSTRACT:
A portable air filter and absorber device for removing impurities such as gases and finely divided solids from the atmosphere includes a sectionalized cylindrical housing containing a blower mechanism operatively connected to a motor driving section. An activated carbon section is detachably mounted adjacent the blower section for removing odors and noxious gases from the atmosphere and attached in series to the activated carbon section is a fibrous section which acts to filter particulate material from the air prior to its entry passage into the carbon granule section. The sectionalized cylindrical housing includes a plurality of inner annular grooves which are adapted to matingly engage projecting end portions of the carbon granular section and the fibrous filter section to permit predetermined mounting of these sections in series to the housing.
