Air Washers William Reed Engineering Co. Incorporated 50 Church Street New York Branches in Principal Cities Factory and Engineering Depts. LOUISVILLE, KY. REED AIR FILTERS PATENTED MAY 16. 1922--OTHER PATENTS PENDING The Reed Air Filter--an all metal filter--operates with inexpensive chemicals by an entirely new combination of fundamental principles. It is the result of exhaustive laboratory tests and three years successful operation in various fields and operates on fundamentally the same principle as the human nostril. Air in passing thru the filter impinges on a media saturated with simple chemicals, dirt and dust are leeched out and deposited on the filter body. The cell and its filter media are practi cally indestructible, both being coated with an enamel which is baked on at high temperature. Removing Unit for Cleaning 186 Size............
