The liquid barrier filter: total protection against particulate contaminants.
The design, construction, and operation of a new type of filter that eliminates particulate contaminants from a current of gas is described. It has a yield higher than that of any conventional filter or filtration system. It is believed that a liquid barrier filter provides the best possible protection in all cases where not even a small number of toxic particulates can be tolerated in an atmosphere.
