Re: Covid band rules
FYI the MERV-13 material can be found on Amazon. It's meant for people who like to make their own air filters for their homes. (Never even had a clue that people did that before this!) I ordered a package of it and have been using it to make filters for my own personal masks. One thing to note that one of their later presentations discussed is that the MERV13 needs to be thought of as disposable. After 3 washes it does nothing much filtration wise since it breaks down the electrostatic charge the fabric has.
With the clarinet bags that everyone got really caught on... On one of the other sessions I've been on with the researchers they discussed that someone sent them to them, so they tested them. One of the grad researchers was a pretty good clarinet player in HS and helped test the protocols. Her comment was that they still leaked from the arm holes, and were entirely unpractical. Bell covers are what the study has been suggestion for that reason.
