FAQ
1.The UV light really can sterilize? Is it available for the new type virus?
It has been a long time since the use of ultraviolet rays to sterilize in Medical history, but it does not mean that all ultraviolet rays can be used to sterilize, only the wavelength 200-280 nm is workable, we call UV-C. Ultraviolet rays can kill almost all germs, viruses, just need different working time and light intensity.
2. Is there any pollution or remaining after sterilizing?
Ultraviolet rays are the most environmentally friendly way to sterilize, no pollution or remaining.The working principle is that the ultraviolet rays destroy the DNA, to prevent the germs and virus from spreading.
3. How long is the working time?
It depends on the intensity of the Ultraviolet rays, UV intensity means the light intensity works on per unit area, the unit is uw/cm²
4. What does UV light use to sterilize? What is the range?
Yes, the UV light can sterilize all things, but should under the ultraviolet rays working range. Actually,the UV is light, so it is easy to understand, if more close to the light, and the smaller working range, then light will be more intense, if larger working range, means light is much weaker, then needs more time to sterilize.
