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. UVC lamps are particularly useful in deactivating microorganisms that are resistant to conventional chemical disinfection methods. 4. Application: Suitable for small-scale applications such as air purifiers, microwave ovens, refrigerators, sterilizers, humidifiers, dental instruments, and washing machines.
