Mask
If you choose to use one, here's how to make it work best.
1. Wear an N95, KN95, or higher rated respirator
Most disposable masks can be used for about 40 hours open_in_new before disposing.
Caution: Counterfeits exist. N95project.org open_in_new directs to vetted providers of certified masks and PPE.
Tips:
ReadiMasks open_in_new are strapless and metal-free; great for barber visits, MRIs, etc. They can even be adjusted to fit over just the nose open_in_new for dental visits. You can also get them in bulk open_in_new.
Here's the best price I've found for the 3M Aura 9205+ from a 3M certified dealer open_in_new. I find this model most comfortable.
If you need N95 masks but are unable to get any, please let me know.

2. Fit check your mask
Make sure you haven't sprung a leak.
