Developing a Novel Method for Disinfection and Sterilization Using a Charged Ozonated mist

The purpose of this research is to find a new method of disinfection and sterilization using safe levels of ozone. This method should not use any drugs or require complicated devices and expensive materials. It should be small in size, affordable, and easy to use. Additionally, this method can effectively kill germs and viruses carried on the surface of the human body, objects, and air, and can potentially be used to kill viruses and bacteria in the respiratory tract. The charged ozone water mist produced by the prototype (ultrasonic mister) humidifier and the high-voltage electrostatic generator can kill the bacteria and viruses on the skin or the surface of the object in a short time (3-20 minutes). Its sterilization rate and inactivation rate reach 90% and 99%, respectively. In addition to a specially designed device that can quickly generate and maintain an ozone concentration of not less than 0.6mg/L, the continuous micro-discharge between negatively charged water mist particles and positively charged skin or objects will also damage the bacteria or viruses. The electric shock effect significantly improves the disinfection and sterilization effect of the ozone water itself and shortens the action time. In addition, the charged ozone water mist can effectively purify the indoor air. The next step of this project is to study the effect of water mist on the killing of microorganisms and viruses in the air, especially the research on the inactivation of human respiratory viruses.
