Air Purifier is an indoor device, not like UVC lamps or tubes, you do not need to leave the room when you open it. The exchange device inside will do the air purification in the machine. There are UVC tubes and ion inside, it will simulate the mountain air in the program.
How high-energy ion works?
The high-energy ion tube uses a specific voltage to convert electrons in particulate atoms in the air into charged ions. When the air passes through the ionization tube, millions of positive and negative ions are formed. The quantity of these ions has been accurately calculated and measured to simulate the air environment in natural mountainous areas. In addition to making the indoor air fresher, it can also effectively solve the problem of indoor air pollution.
I believe that air purifier is suitable for escalator, elevator, factory, and other opened facilities.
