  4. Ozone generator disinfection is divided into miniature, namely, low ozone production, which is used for sanitation and cleaning, or small space disinfection; Large, even if the ozone production is large, it is used for indoor air disinfection. When the relative humidity is ≥ 70%, the ozone concentration is 4~6mg/m³, The working time is 60min, which can meet the disinfection requirements. Ozone is corrosive to metals, accelerates the aging of rubber and plastics, and is toxic to people. People must leave the room during disinfection.
