  • Patent number: 10478767
    Abstract: A method of air purification and apparatus uses thorough air-bath to trap airborne debris and gaseous molecules in the liquid. Incoming air are reduced repeatedly and thoroughly at various stages into tiny air bubbles in contact with liquid in the apparatus where airborne materials and gaseous molecules are trapped in the liquid. This cleaning system can effectively remove small or large airborne debris and gaseous molecules, in contrast to cleaning effectiveness limited by the filter pore sizes in traditional filter system. The liquid can be water, water mixed with any designed substances or other type of liquid phase of materials. In exemplary case, water is used as a part of filtration medium, the apparatus thus can be served as both air purifier and humidifier. A relatively high humidity in the air would help to trap more airborne debris, which makes the air purification apparatus more efficient.
