Introducing faruvc.org

Jeff Kaufman 🔸

I wanted to link an explanation of how far-UVC works, why you might want to use it to clean indoor air, and what we know about its safety. I didn't find anything I liked, so I made something: faruvc.org.

You can also link it as far-uvc.org; I got both domains since the hyphenated one reads better but is a bit longer.

Let me know if you have ideas for making it better! My goal is to have something anyone can understand, without simplifying so much that it's misleading.

At some point I'd like to include an illustration showing far-UVC in use in an occupied space, but I don't have one I like right now.

(While I'm an employee of SecureBio, this is a personal project.)

I kept wondering "how does this compare to sunlight" in terms of radiation that reaches the living layers of your skin, etc. Might be worth including that.

Good question! Reworded a bit:

Far-UVC's strongest effect on viruses and bacteria is to damage their proteins, so they can't infect us. This same protein absorption is what makes far-UVC safe for humans: unlike the UVA and UVB in sunlight that penetrate deep enough to cause sunburns and skin damage, far-UVC is so strongly absorbed by proteins in the dead outer layers of our skin and eyes that it doesn't reach the living cells beneath. Because of this shallow absorption, far-UVC has minimal effects on the human body, and is safe to install in our homes, schools, and workplaces
