My #university #AcademicEmployment doesn't provide #CO2Level indicators in #SeminarRooms, & only "recommends" #masks so 3/4 of my colleagues run around maskless in un-aired spaces. I see 96 students/wk. 🤐

Carted a small HEPA filter to my seminars & wore a FFP2 mask. Felt like a freak but the Covid I got (my 2nd time) was from my SO's train commute.

Now have invested in a far-UV 222nm desk lamp which I will employ additionally.

I'll be damned if Covid gets me a third time. #KeepFightingCovid
