The lamp will produce only a minor amount of ozone. At such low concentration, ozone will not cause any harm to the human body. During the operation of the UVC lamp, there will have a very weak distinctive smell in the room. This particular smell comes from organic materials such as bacteria and mites that are burned by ultraviolet light. In general, this smell will disappear quickly. If you don't like this smell, you can wait 30-60 minutes.

Avoid touching the lamp tube; it might reduce the lifespan of the lamp. People/pets/plants can’t be exposed to the UVC light and must leave the room when the lamp works.
