ABSTRACT:
An air filtering apparatus for obtaining high purity purified air by separating diffused particles from air, including a fibre filter, an upper porous plate, a lower porous plate, and a purification means fixed between the upper porous plate and the lower porous plate. The air carrying bacteria and dust particles is purified by the pre-filtration of the fibre filter and the re-filtration inside the electric field of the purification means. The apparatus is particularly useful in the production of monosodium glutamate, citric acid, enzymic preparations of the foodstuff industry and other industries and obviates filter orifice blocking, permitting longer operating life.
