Disinfection spray is a common method for disinfection of air and object surface in closed environment. For example, the new guidelines for the use of disinfectants issued by the new office of the Health Commission clearly put forward that peracetic acid or hydrogen peroxide spray disinfection is an effective disinfection method. Compared with peracetic acid, the hydrogen peroxide sprayed by the hydrogen peroxide disinfection machine is milder. After the outbreak of COVID-19, hydrogen peroxide disinfectors have been used more and more widely. Used for air and object surface disinfection.

Both peracetic acid and hydrogen peroxide disinfection machines can be used for disinfection, but according to different principles, there are two commonly used hydrogen peroxide disinfection methods sprayed by hydrogen peroxide disinfection machines on the market. One is to vaporize hydrogen peroxide, and the other is hydrogen peroxide dry fog, namely hydrogen peroxide spray aerosol. These two methods are completely different. Vaporized hydrogen peroxide is formed by heating and flash evaporation of hydrogen peroxide above 110 ℃ to form steam, which is completely gaseous and diffuses in the air. Atomized hydrogen peroxide is a high-pressure nozzle or ultrasonic wave that disperses hydrogen peroxide solution into 3-50um aerosol liquid particles suspended in the air and diffuses in the form of Brownian motion.
The disinfection methods of peracetic acid or hydrogen peroxide disinfection machines are very similar, and many experts cannot distinguish between them. But hydrogen peroxide disinfection machines have been widely used in the market, praised by consumers for their safety and good disinfection effect!
