far-uvc

Well, one reason KrCl lamp life became an issue is that they are not replaceable in any commercially available filtered Far-UVC fixture.

Studies suggest that a single activated carbon filter is more than sufficient to mitigate any far-UVC derived ozone.

Far-UVC lamps deactivate airborne pathogens, but cannot penetrate the human eyes or skin making them generally safe to use.

Which should make installation and deployment of far-UVC both more practical and economical in the future.

I also don't think the world is going to move to UV-stable polymers for everything just to make far-UVC work (in some cases this isn't even possible).

Most likely, you will raise your indoor ozone levels much more by opening a window than by operating a far-UVC lamp.

I do not believe that there is a good understanding of the impact of far-uvc on plastic embrittlement.

According to this [1] article, the 222nm range is safe for exposure, but the Krypton-Chloride bulb in the far-UVC lamp does also produce harmful wavelengths (256nm), therefore a filter is absolutely necessary.

It's worth noting that the premise of the article- that low cost Far-UVC could not easily be purchased before the Aerolamp, is false.

Edit: Come to think of it, filtering the harmful UVC (256nm) from KrCl excimer lamps with acrylic would probably also block the far-UVC.

Given that fraudulent claims in the Far-UVC industry are common, there's every reason not to trust marketing claims that aren't backed by third-party tests.

At which point virtually every Far-UVC company started claiming everything from 5,000 hours to 20,000 hours operating life- with absolutely no data to support this.

If someone says anything about their Far-UVC lasting more than 5,000 hours, the correct response is "Citation?".

I don't think "stop using polymers in any place where far-uvc may exist" would fly.

Any other manufacturer is welcome to use them as well, with the hope that this will get Far-UVC ownership down to the "rice cooker or oscillating fan" price range needed for those in the most desperate need.
