Abstract: A fan draws an air stream or path, contaminated with bacteria, fungi, or viruses into a hygienic treatment device. The device includes a perforated cartridge initially confronting the air stream and carrying a plurality of silicate pellets therein. The pellets are impregnated with a germicidal agent before emplacement in the cartridge. A stack of parallel, spaced plates separated by phenolic wafers are positioned closely adjacent and slightly downstream from the cartridge. A voltage of at least 4,000 volts is supplied to the stack of metallic plates. The moving air stream generates a siphoning action on the pellets to better withdraw the germicidal agent therefrom. The germicidal agent, which is preferably a grapefruit seed extract, destroys the bacteria, fungi, and viruses, and causes airborne particles to become positively charged. The contaminated airborne particles are then collected by the negatively charged plates in the stack.
