高功率深紫外线杀菌器(20 surgical masks included with each purchase)
This machine is professionally made to combat coronavirus with the following unique features:
1. Our machine contains a 13W UV light bulb in a compact size; similar machines have only 8W. UV light kills viruses by destroying their ability to reproduce. But it needs sufficient power.
2. Our machine uses a quality Quartz UV light bulb that extends the UV spectrum shorter than 250 nm, which is required to kill the virus. The effectiveness of UV radiation to destroy viruses has been scientifically verified. However, this virus-killing function is most effective in the 250nm wavelength band since it requires high energy photons and good organic matter absorption. As shown in the figure below, current consumer UV based machines on the market that are intended to kill germs all use glass-based UV bulbs that block this wavelength range, thus having a limited effect on viruses.

3. It has a timer from 1 to 60 minutes so that your items can be automatically disinfected.
4. This product is suitable to face masks, cellphone, wallet, key chains and other small articles such as glass, metal or plastic stuff.
