Q: What is UV-C light and how is it different from other UV lights?

A: There are three types of UV rays

UV light has three wavelength categories: UV-A, UV-B, and UV-C. UV-C light is a short-wavelength, ultraviolet light that breaks apart germ DNA, leaving it unable to function or reproduce. In other words, UV-C light is a natural sterilizer (UV-A and UV-B light are not). UV-C can even kill 99.9% of microbiomes (germs, bacteria, and viruses)

Q: When did people start using UV-C to sanitize?

A: For hundreds of years!

People have been sanitizing with UV-C light since the turn of the century. In 1903, a Nobel Prize in Medicine was awarded to Niels Finsen for incorporating the use of UV light in battling tuberculosis. Today, medical centers, labs, and facilities use UV-C sanitizing lights to keep their environments sterile and safe.

Q: Is UV-C safe for humans?

A: Yes - when used with caution

We can't stress this enough. A UV-C sanitizing device is not a toy. When used on the human skin, the UV-C rays will cause irritation and long term exposure can lead to skin damage. When using a UV-C sanitizer, ensure that you're pointing the UV-C light down and away from you. When UV-C sanitizing lights are used in moderation with caution, they are safe for human usage.

Q: Can I use UV-C for any surface?

A: Yes!

UV-C sanitization can be used on any surface including utensils, eyewear, toys, and clothes. For best results, sanitize for 10 - 15 seconds hovering 2-3 inches away from the surface of the item that you're sanitizing.
