Got my 4 tests yesterday

I have yet to try any of these; usually just go with a blue surgical one or a cloth one. Are these ok to breath with in continuous use? Compared to blue surgical ones

In NYC covid contact tracing is huge. I don’t really get the point of it now that so many people are testing at home and don’t report their results anywhere.
I tested positive at home 2 weeks ago with 3 at-home tests and towards the end also went for pcr testing. The 2 days I tested negative, I got my pcr results and 2 days later got a call from NYC Test&Trace and was asked to provide all sorts of info; with whom I have been in contact, where I have been, my symptoms, how I feel now etc etc.
I just feel it’s such a pointless waste of resources!
