UV based sterile lamps now have the power to sanitize your home and other indoors like schools, hospitals, and offices with the short wave UVCs. As it could get, there is absolutely no secondary pollution. Ultraviolet rays are believed to kill the many bacteria and other microorganisms in the air by destroying microbial DNA and RNA. The total power consumption of these bulbs is around 38 watts, but it is preferred to use it for more than 40 minutes per day.
