Today was the first day I stayed in a hotel since the start of the pandemic. I thought some people might like to know my respiratory protection strategy.
2-
First, I picked a hotel that had individual HVAC connected to the outside.
3- When I arrived, I immediately turned that fan on but kept my respirator on. I then did a qualitative assessment of airflow the same way I do in hospitals to verify that positive and negative pressure rooms work correctly.
4- Take a piece of tissue and separate the plies and tear it to about 1/4-1/3" thick. Slide it down to the crack in the door at the floor to see which direction air flows. You can see the tissue didn't move, ie, static pressure.
5- I then turned on the exhaust fan in the bathroom to see how that changed the pressure dynamic. It made my room negative pressure in relation to the hall.
6- That meant I needed to block the gap under the door because whenever I would go into the bathroom, it would draw hallway air into my room. Still had my respirator on.
7- You can also see I put my small HEPA filter near the door as well. I then left my room to pick up some dinner. About 20-30 minutes elapsed before I got back. Between the AC pulling in fresh air and my HEPA filter running, I felt very comfortable without my respirator on return
