UVC disinfection is not a scam. There are many scientific studies proving UVC light kills almost all kinds of germs, including from the CDC and EPA.
One study of UVC disinfection using the same wavelength and power as Uvlizer is called ‘Surface Disinfection by Exposure to UV Light’ in the Indian Journal of Medical Microbiology. This study showed that ‘UV light has efficient inactivation of bacteria up to a distance of 8 feet, and an exposure time of 30 minutes is adequate.’
