Abstract
An air purifier is disclosed having a bubble generator configured to generate fine air bubbles with a diameter of about 50 μm or less and a negative electrical charge. The bubble generator is coupled to an air purification tank, which contains a liquid for purifying the air within the air bubbles, by dissolving impurities. The tank also has a positive electrode disposed within the liquid. The positive electrode is configured to attract the negatively charged air bubbles, thereby promoting defoaming and increasing the air throughput rate.
