In terms of far-UVC 222nm disinfection, I've only found this pendant that is actually purchasable. It's still meant for commercial use, but we could put it in our dining room. It's a wee bit spendy...

Quick internet searching today for far UVC 222nm lights for my house... didn't really turn up anything. Most still seem to be for commercial applications. I have some emails out about how to actually purchase these products.... we'll see! #faruvc222nm #CovidIsNotOver
