The weather forecast always talks about ozone pollution index. Is this related to household ozone disinfection?

How can matter be described as good or bad?

Everything has two sides. Let's see how it works!

1, trace ozone has the functions of sterilization and detoxification, and is often used as a disinfectant with less residue.

2. At the same time, ozone is one of the industrial waste gases, which is often produced in the production of electronic industry. The ozone concentration that people are allowed to contact is not more than 0.2 mg/m3. Excessive ozone can cause neurotoxicity, dizziness, headache, vision loss, memory loss, damage to human immune function, induce lymphocyte chromosome lesions, accelerate aging and so on.

3. Most of the ozone mainly exists in the ozone layer below the stratosphere 20 kilometers away from the earth's surface, with a content of about 50ppm. It absorbs short-wave ultraviolet rays harmful to human body and prevents them from reaching the earth, thus shielding ultraviolet rays from life on the surface of the earth.

Therefore, there are strict standards for household ozone disinfection:

The leakage of ozone shall not exceed 0.2mg/m3 (1.5 meters away), and the residual concentration after one cycle of disinfection shall not be greater than 0.2mg/m3.
