UVC Sterilization Technology emits high-intensity ultraviolet UVB to irradiate the air. When irradiated on each surface of the room, it can decompose Oxygen O2 molecules in the air and the generated O atoms are then combined with O2 molecules to generate ozone O3. Ozone O3 can destroy the cell wall of bacteria, penetrate into the cell and destroy them, achieving the effect of sterilization. UVC can eradicate any microorganism or pathogen including MRSA, cold and flu, mold, E.coli, salmonella, COVID-19 and similar types of bacteria. No microorganisms are currently known to be immune to UV-C and UV-B energy.
