At present, most high-purity areas such as hospital wards, operating rooms and pharmacies use ozone disinfection instead of traditional ultraviolet disinfection and disinfection water disinfection. Generally, there are many ozone generators and wall-mounted ozone sterilizers in central air conditioning, which save space and are convenient for patients and doctors to see a doctor.

The wall-mounted ozone sterilizer does not need manual control, and it can realize man-machine automatic operation through intelligent alarm and microcomputer controller to realize man-machine integrated disinfection. This kind of ozone generator used in central air conditioning system must be disinfected when no one is working. Now, hospitals are increasingly using ozone therapy instruments to treat diseases and clean pipes. Ozone generators in Qingdao, Shandong, Huanwei, Guangzhou and Jiangxi are also used in many hospitals.
