1 Do you really need a UV lamp?

If you are in an environment that is not very good, such as dusty, prone to moisture and mold, etc., it is recommended to buy UV lamps, because their energy is very strong and can destroy 99% of bacteria and viruses in the air, water and object surfaces. In particular, there are some experts who believe that the UV disinfection lamp can also kill the new crown virus to a certain extent. If you usually live and work in a relatively clean environment, then there is actually no need to buy UV disinfection lamps.

2 What is the difference between ozone UV lamps and ozone-free UV lamps?

First of all, Ozone can also be disinfected:

  • Ozone has an extremely strong oxidizing effect
  • It can react with the double bonds of lipids in bacterial cell walls
  • Alters cell permeability and causes death with high efficiency

The principle of ordinary UV disinfection lamps is UV-C direct irradiation of bacteria and viruses caused by their death, belonging to the physical disinfection, and UV-C wavelength is very short, so the penetrating ability is relatively weak, encountering complex space, it is easy to disinfection dead ends, so some UV line disinfection lamps will add ozone function because ozone is a gas, it is difficult to exist dead ends, just to make up for UV-C this shortcoming.

Then since ozone can make up for the disinfection of ordinary UV disinfection lamp dead ends, the cost of ozone generation is not high, why not all UV disinfection lamps with ozone function?

Because although ozone can sterilize, at the same time will also stimulate the human respiratory tract, may cause sore throat, chest tightness, and cough, bronchitis, and emphysema, etc.

Therefore, the use of ozone disinfection must have a condition that the space is well ventilated so that the ozone can be dispersed.

The use of UV disinfection lamps with ozone is highly discouraged in poorly ventilated spaces.

AdvantagesDisadvantages
Ozone UV lampOzone has a strong oxidizing effect, which can effectively kill bacteria, and the diffuse nature of ozone can just make up for the shortcomings of disinfection due to UV light only spreading along a straight line and having dead ends.The ozone is an invisible killer! It strongly stimulates the human respiratory tract, causing sore throat, chest tightness and coughing, bronchitis and emphysema, and requires opening windows for ventilation after disinfection.
Ozone-free UV lampsno ozone, sterilization is completed, people can immediately enter the room.Only along with the straight-line propagation, disinfection has a dead end.

3 Conclusion

So the conclusion is that the UV disinfection lamp with ozone is relatively better, disinfection will be more thorough, but at the same time the conditions of use are also more stringent, so you still have to use the scene to decide to choose the UV disinfection lamp with ozone or without ozone.

The effect of ozone is better, the use of ozone is more troublesome, at least 30 minutes ventilation. Need to confirm whether your environment is ventilated, ventilation is not good, then use the oxygen-free type of safety.

Recommend several cost-effective UV disinfection lamps, you can select with ozone or without ozone, have a three-timer, remote control switch through the wall, and the service life of about 8000 hours, very good.
