WHY UVC STERILIZER
&
Does UV sterilizer work?
UV sterilizer is acknowledged as a professional technology
UVC has been widely used in cupboard sanitizer and sterilizing decices in hospital for 60 years. UVC LED light eliminates almost all the germs and bacteria by destroying DNA & RNA physically.

Sterilization process visualization
UVC LED sterilizing process can be seen under a microscope

Sterilization effect to smell
UVC LED light can reduce smells by decomposing the molecular structure of odor, such as milky smell of feeding bottle, residue of medicine, sour smell of drinkware and etc.

DIY Experiment
Cut an orange in half, keep storage at temperature 25℃~30℃.
Exposing one half in UVC light, and leaving the other half aside.
The changed will be observed in 2~10 days.(Not intended for retaining freshness)

UVC LED sterilizers v.s. Other UV sterilizers in general
1. Same sterilization principle ---Both of them are killing bacteria by exposure to UVC light. The UVC LED is designed to emit UV light at wavelength of 260~280nm, which is of at least 50% higher efficacy than the normal UV tube one, save more time as well.

2. Doesn't damage the bottle by UVC Sterilizers ---Every UVC Sterilizer is built-in timer for 3mins' sterilization process, so it's not continuously exposed under UV light. The lab data shows that material won't be aged until 500hours' continuous exposure. So intermittent sterilization is ok.

3. Steamed, electrical sterilizers, or simply boiling in water for a minute is an alternative choice, but not the best way. You can't assure to have boiling water, electricity, etc. at any time. So it's more convenient and easier to take the UVC Sterilizers both indoors & outdoors anytime.
