What is UV-C?

UV-C has been known for 100 plus years

UV-C has been known for 100 plus years to be effective at killing viruses. It is successful at killing 99.9% of all living organisms by denaturing its DNA/RNA making it unable to infect or replicate. But it poses a threat to human skin and eyes.

The Science

Radiology expert from Columbia University Dr. David Brenner worked with our manufacturing partners Ushio to develop a safe wavelength that can kill viruses and is safe around people. This is referred to as Far UVC or 222 nanometer UV. 8 hours of exposure to our Far UVC light can be compared to 15 seconds of exposure to sun light. A safe way to disinfect our indoor air. Here are the results of our studies and the tests we’ve conducted in the last few years.

What about Ozone production?

It is key to note at 222 nanometers Far UV-C lights do produce a bit of ozone. The best way to avoid ozone build up indoors is to have constant air flow. With proper ventilation you can reduce ozone by 98% indoors. With our Care222 devices you will not have to worry about ozone build up since we have carbon filters reducing ozone by 70%. But it is still recommended to make sure you have air flow as you would even without Far UV-C.
