Question for Midnight Rambler - IIRC ur in the HVAC biz?

this sizable vlogger "Fullerton Informer" aka Joe Imbriano,

YT (122K subs): https://www.youtube.com/c/TheFullertonInformer/videos
BC: https://www.bitchute.com/channel/rzA0DKRPzpzd/

he has this 34 min vid up:
Why The Schools Are All Fenced-in Like Prisons

where he says there's a new-ish aircon tech which skools are being aggressively 'upgraded' with, esp while they were closed since March -- in addition to 'upgrading' their 5G which already widely made the jooflu19-skeptic community rounds.

Aircon 'upgrades' = adding a "purification element", a "cold plasma reactive oxygen species generating system."

Begin 8:45 above for where he picks up the ("weaponized...") aircon-system upgrades part.

U know anything re Joe's veracity on this aircon claims?
