a modular , integrated , combination air purification and aroma diffuser includes a uv and catalytic oxidation germicidal cell and multiple filtrations as pre - treatment of air diffusing essential oils or other liquids as ultra - fine droplets entrained in airflow into enclosed , habitable spaces . liquid microbicide , insecticide , fumigant , or aroma therapy is kept cleaner by eradication of microbes . comparatively larger droplets are separated out and recycled to the reservoir after initial atomization . an electrical module , between a purifier and filters upstream and a diffuser downstream , includes a pump , a fan , and a controller for both . staged , double - eduction , triple - separation processes include a micro - cyclone for quiet , well diffused flow of ultra - fine droplets .
