#222nm — Public Fediverse posts

@debihope @BlackAzizAnansi I bought a Kickstarter #Mask in 2020 that shines UV light on the air as it goes in the mask, but not for long enough to kill #Covid. If the UV LED was outside the mask, it would do a better job of disinfecting the air, but then it would burn or blind me - it uses 254nm UVC light, the same kind tanning beds use.

What I really want is a mask or a headlamp with the new #222nm LEDs. 222nm UVC light kills Covid in minutes, but can't burn skin or eyes like 254nm.

@SexyCyborg is a #maker in #Shenzen who built a personal 222nm projector: http://tny.wtf/Y Naomi is a great person to follow for her insight on fighting Covid.

Unfortunately, 222nm lights cost $$$ everywhere that isn't Shenzen. In the US I can get a 20w 254nm bulb for $20, but a 20w 222nm light is $1000-$2000.

If the US took disinfection seriously, we could jumpstart a 222nm industry and put them in light fixtures everywhere for cheap, but we don't take much about Covid seriously.
