2.      Efficient bactericidal broad spectrum: The broad spectrum of ultraviolet disinfection is the highest, it is almost can kill all of the bacteria, viruses with high efficiency.

3.      No secondary pollution: UV sterilization does not add any chemicals, so it will not produce secondary pollution to the surrounding environment, do not change any component of the air.

4.      Safe and reliable operation: Traditional disinfection techniques such as using chloride or ozone, the disinfectant itself is highly toxic, flammable substances, but UV disinfection system does not have such security risk, and dynamic disinfection can be done for indoor air when someone is in room. (Ozone disinfection must be carried out when nobody in room. Ozone concentration is low, the eye, nose, throat irritation; Concentration 1-15PPm, there will be headache and respiratory local paralysis and other symptoms. Ozone toxicity is related with contact time, generally when contact time is no more than 2 hours on the condition that concentration less than 20PPm, no permanent damage to the human body. If you feel uncomfortable, you can blow out the air, breathe fresh air.)
