Coming in with the anecdotes, but I've done a public facing job with often just the carrageenan spray as prevention in small unventilated spaces face to face with clients for 6 months now and never got sick from work.

I did get covid, but from family via my partner at home.

The last time I had to spend an hour with a visibly sick person was at the start of this week and so far so good. Might be immunity too from having just had covid a little over a month ago though. I wish masking was ok in my work, but it's not.

But considering how high risk my work is and how all my co-workers sure are sick all the time and I'm not, it makes me think the spray might at least be helping. I also avoid gatherings and have an air purifier on my desk, I also don't people on my freetime. So there are many reasons for this as well.

so it's enhanced snot.
