Description

  The present invention relates to an air purification apparatus that uses discharge and water to remove malodorous substances and harmful substances in the air, and bacteria and allergens.

  Conventionally, an air purification device that uses discharge and water to deodorize and sterilize introduces water vapor into the discharge area and oxidizes by collisions between electrons and water molecules scattered at high speed by discharge, ultraviolet rays, etc. Strong OH radicals are generated, and the malodorous components and harmful substances are decomposed, and in addition, the bacteria and viruses in the air are inactivated and the DNA and RNA are destroyed to prevent breeding (see, for example, Patent Document 1) ).

In addition, water that contains water in the water reservoir is atomized to atomize the water containing it together with radicals with high oxidizability, and are released indoors to deodorize attached odors such as indoor air and indoor walls. Yes (see, for example, Patent Document 2)
