What are the precautions when using ozone disinfection?

1. People must leave the scene during ozone disinfection: ozone has obvious killing effect on microorganisms in the air, including coronavirus, but the concentration of ozone needs to reach 20mg/m3 to achieve disinfection effect. However, the safe ozone concentration for human beings is 0.05ppm (or 0. 1mg/m? )。

2, can not be used beyond the volume range: different models of machines have their maximum disinfection range, ozone sterilizer disinfection can not exceed its specified disinfection volume range, otherwise it will affect the disinfection effect.

3. The higher the humidity, the better the disinfection effect: the higher the humidity, the better the ozone disinfection effect, which is generally required to be above 60%. This is because the cell membrane swells and thins under high humidity, and its tissue is easily destroyed by ozone.

Benefits of ozone disinfection

1, high efficiency: this disinfection method uses air as coal, and does not add any other auxiliary materials and additives, so it has the advantages of good compatibility and thorough sterilization, and also has strong performance of removing musty, fishy and peculiar smells.

2, high cleanliness: ozone, with the characteristics of efficient decomposition into oxygen, is a unique advantage of ozone. Ozone is formed by using oxygen in the air. During disinfection, excess oxygen will form oxygen molecules after 30 minutes without any residue.

3. Convenient: the equipment can be disinfected according to the set time, which saves the trouble of manual operation.
