Bluezone by Middleby is air purification that finally works. Bluezone uses the precise balance of ultraviolet-enhanced oxidation between 185nm and 254nm to destroy airborne contaminants, such as odors, mold, bacteria, and virus. Bluezone does not rely on mechanical filtration, instead Bluezone scientists have maximized the flow rates and residence time though the Bluezone unit in order to get killrates between 99.9% and 99.9995% depending on contaminant and unit type.
