1. At present, most bottled water manufacturers use ozone for disinfection. Ozone can be decomposed into oxygen in a certain period of time, which is harmless to human body.
Bottled water should not be drunk immediately after it is filled with ozone. Ozone can only be drunk after it is fully decomposed (8- 16 hours). However, in some small enterprises and small water shops, it is irresponsible to send bottled water to customers as soon as it is full.
3. It is suggested to change the brand of water delivery store or bottled water, and find a bigger water store and a well-known local bottled water brand.
