1. Quartz glass refers to ozone-free operation; use incandescent lamp or special capacitor connected to 220 V / 50 Hz or 120 / 60 Hz main voltage line without ballast; switchable up to 20,000 times 2. It destroys the DNA structure of microorganisms, rendering them unable to reproduce, and thereby inactivates bacteria, viruses, and other pathogens. 3. Ultraviolet UVC light can effectively eliminate most bacteria and microorganisms in air and water within seconds.
