The basic requirements for the safe use of an ozone generator are as follows:
Yes, it is safe to use ozone for the sterilization of food. Ozone received a GRAS (Generally Regarded as Safe) approval from the U.S. FDA in 2001 and later a GRAS approval from USDA in 2002.
Yes. But compared to use it in other spaces, its working time in the car should be controlled. A good tip is to limit the application time to 20 minutes or less. In addition, in order to avoid the impact of ozone on the rubber and leather materials in the car, instead of using ozone gas, it is suggested to use ozone water to wipe the interior of the car for a sterilization or odor removal purpose.
Whether ozone gas will affect a material is determined by the nature of the material itself, but also by ozone concentration, air humidity and whether the material has been treated against ozone and other factors. The following are indicators of the effects of ozone on different materials:
Rating Key
A = Excellent - Ozone has no effect on the material.
B = Good - Ozone has little effect on the material. Can be used at low ozone concentrations or for short periods. However, long time or high concentration of ozone may still cause erosion of the materials.
C = Fair - Ozone has a moderate effect on the material. These materials should only be used in low-level ozone environments or for short-term applications. Prolonged use will cause erosion of the material.
D = Poor - Ozone can have a serious effect on materials. The material will decompose in a short time (a few hours to a few days).

There is. However, most medical applications are not approved by the FDA. So, we do not recommend them until there is more research to prove it. On the other hand, ozone can be personally used for health care. For instance, you can use ozone water to wash face or have an ozone bath. There is also ozone olive oil.
Yes, this is a question that end customers often ask while purchasers rarely care about. It is certainly not safe to breathe a high concentration of ozone. Therefore, except for very low ozone yield models that meet EPA guidelines, we recommend using ozone in environments where there are no person, animals or plants. In addition, it is recommended to allow at least 30 minutes for ozone diffusion before re-entering the room. Therefore, it is a good time for an ozone treatment while you are out. An ozone generator will not pose any health risks as long as it is used following the user manual.
