ABSTRACT:
A portable gas cleaning unit having a box-shaped housing supporting filters operable to remove particulates, pollens, odors, and smoke from a gas, as air. A motor driven fan located within the housing moves gas through the filters and discharges cleaned gas to the environment outside of the housing. In one form of the invention, the motor is a D. C. motor powered by a 12-volt battery. The filters are mounted in a recess in the top wall of the housing and include a coarse fiber filter and a particulate charcoal filter. A protective open rectangular grid is located over the fiber filter and is mounted with a tight fit on the top wall to hold the filters in the recess. An open top tank is located within the housing for carrying a liquid, as water. Vapor plates mounted on the tank are used to facilitate the evaporation of liquid into the gas flowing through the housing. The tank has a longitudinal extension adapted to move through an opening in a side wall of the housing to allow liquid to be placed into the tank.
