ONE43UV uses the power of UVC light to sterilize, sanitize, and disinfect multiple surfaces. It is portable, rechargeable, foldable, and effective. The efficient design of the wand makes it large enough that it covers more surface area than any other UV wand in the market. With ONE43UV, you can sterilize without any odor or the use of any chemicals. It also has a built-in gravity sensor that automatically shuts the light off when tilted 90 degrees.UVC is on the spectrum of UV light. You might be familiar of UVA and UVB. They are higher on the UV spectrum. UVC is lower on the spectrum so the wavelengths are shorter which are much more powerful and damaging to the skin. Natural UVC from the sun is absorbed by the ozone layer so it never reaches us. The way UVC works is it alters the DNA and RNA of organic cells like germs, bacteria, mold, and viruses which stops them from reproducing. ONE43UV uses 270-280nm of UVC light. The longer a surface is exposed to the light, the more germs, bacteria, etc. is diminished. UVC is nothing new. In fact, it has been used for many years in hospitals in addition to their cleaning protocols. Science has proved the effectiveness of UVC light in disinfecting. UVC light can still be dangerous if exposed to the skin or eyes of humans or even pets. So be cautious when using!
