To give you an idea of how does the UV light works, let me start by saying that there are three UV light wavelength categories: UV-A, UV-B and UV-C. The UV-C wavelength is different as the first two are longer and not a germicidal while the UV-C light is shorter and an effective germicidal wavelength. The UV-C light is deadly to microorganisms because it destroys nucleic acids and breaks apart the germ DNA and as a result, they cannot function or reproduce and the organism ends up dying.
The PhoneSoap XL UV- C light sanitizer is an easy and effective way to avoid the spread of germs and can be used on anything from a pacifier which inevitably ends up on the floor, to a tablet and anything in between. Well the pacifiers, remote control, my phone and my tablet which is the initial intent of this device.
