How effective is UV sterilization?

Let's start with some history of UV sterilization so we have a better understanding. Where does UV come from? Well, UV is a type of radiation that comes from the sun. There are 3 types of UV; They are UV-A, UV-B, and UV-C. Only UV-A and UV-B can enter the earth's atmosphere and these are the UV lights that can cause "sun burns" when exposed for too long. Only UV-C does not enter the earth's atmosphere 

If UV-C does not enter earth then how did we end up with UV sterilization? which requires the short wavelength and power of UV-C? It was not possible until we learned to harvest the power of the sun in man-made sources such as mercury-lamps. By utilizing mercury, we were able to produce the same powerful UV-C radiation that the sun emits.

For decades, scientists have conducted countless research and tests to prove the validity of UV-C irradiation and their germicidal effectiveness. Hospitals and other healthcare facilities have implemented ultraviolet germicidal irradiation systems equipped with low-pressure mercury vapor lamps to disinfect their environment with a sterilization rate of up to 99.9%.

The problem? Unfortunately, traditional UV-C mercury vapor lamps are usually large, expensive, and pose health hazards to humans which prevent its use to the public.

Our solution? Wonder wand utilizes advanced LED (Light-emitting diodes) technology to produce UV-C irradiation wavelengths with the same germicidal effects as traditional mercury vapor lamps without its health hazards. Wonder wand is chemical-free, ozone-free, and mercury-free.

With this technological advance, sterilizing is made safe, portable, affordable, energy-efficient, and easy to access.
