Ozone is a broad-spectrum sterilization, and has strong killing effect on various bacteria and viruses. The strong sterilization capability and no residual pollution of ozone can be widely applied to the aspects of disinfection, deodorization, mildew prevention and fresh keeping in the food industry.

Has great effect on improving food processing technology and improving food quality.
Ozone, as a gas bactericide, produces a strong killing effect on viruses, bacteria, molds and other microorganisms by virtue of its oxidizing property. Like any disinfectant, the disinfectant can cause certain physiological reaction and even damage to animals and human beings, but ozone is much smaller than a common disinfectant, and the disinfectant is much easier to protect environment. Smelling ozone specific odor, "irritation" is a sticky reaction of the respiratory tract, feeling dry mouth, cough, strong irritation with feeling of pain in throat, fatigue, etc., and needs several hours to recover. So far, no death accident caused by ozone poisoning exists in the world. Ozone is used as a disinfectant, has the advantages of strong sterilization capability, capability of self-decomposing without residual pollution, immediate disappearance of discomfort after contact when leaving the site and the like, is incomparable with common disinfectants such as formaldehyde (formalin), peracetic acid, potassium permanganate and the like, and can ensure that the health is not damaged by correctly applying the ozone in a scientific attitude.
Therefore, some ozone generators attached to refrigerators are produced on the market, i.e. their entire circuit system is connected to the refrigerator. Such a design makes it very inconvenient for the user, especially if the ozone generator is damaged alone.
