WHAT IS THE APPROPRIATE CONCENTRATION FOR OZONE STERILIZATION AND DISINFECTION? HOW MANY MG/M3
GB 28232-2020 "Hygienic Requirements for Ozone Sterilizers":
1. Air disinfection ozone concentration: 5 mg/m3~30 mg/m3, relative humidity ≥70%, the effect is 30~120min.
2. Disinfection of object surfaces: Ozone concentration should be ≥60 mg/m3, relative humidity ≥70%, action time 60 min~120 min.
3. When using ozone water to disinfect object surfaces: the ozone concentration in the water should be ≥10 mg/L, and the action time should be ≥60 minutes.
