Even Amazon uses UVC light to sanitize its grocery
stores and warehouses.
UVC light enters the cell’s nucleus, causing irreversible damage to RNA (for viruses) and DNA (for bacteria).
The easier it is to penetrate the “outer layer” of a microorgansim, the easier it is to kill.
Viruses with an outer membrane (called an envelope) are easiest to kill because these organisms cannot live without this envelope.
UVC light easily damages this envelope and the microorganism dies.
Coronavirus is an enveloped virus and is among the easiest to kill.
ALL bacteria and viruses tested to date (many hundreds over the years, including coronaviruses) respond to UVC disinfection.
Some organisms are more susceptible to UVC disinfection than others, but all tested, respond at the appropriate doses.
Dose consists of 3 factors:
Dose determines what proportion of a specific microorganism is destroyed after a particular dose of UV radiation.
Target Dose: 50 mJ/cm2 to deactivate the average bacteria/virus
Viruses are much easier to kill than bacteria and mold, as viruses are much smaller in size. Increasing the dosage time increases disinfection effectiveness.
We sell an inexpensive card that can measure the dosage of any UVC light sanitizer which does not have LED bulbs so you can verify that your UVC sanitizer is delivering the required dose to keep you safe.
UVC light is used by food manufacturers to keep bacteria levels low during processing
New York State bought UVC lights to sanitize buses and subways
Even hospitals trust UVC light to disinfect their working spaces
Because UVC light kills microorganisms, it is considered a pesticide and regulated by the EPA.
Only U.S. residents can legally sell pesticide devices in the U.S. and all sellers must clearly display their company or establishment number on websites, advertisements, packaging and labeling.
Any seller which does not display their number is either not a legal seller of UV light sanitizers or is in violation of federal law. Sellers of UV sanitizers who are properly registered with the EPA are highly aware of the requirements.
You can verify licensure on the EPA website.
UV light sanitization is recommended by the CDC, NIH, FDA and EPA among other authoritative sources.
