I see people post about these, but I don’t see how I would do something based on result. I’m wearing a mask already and I don’t control the ventilation in public.

If you use a CO2 monitor what are you doing differently in response to the results either way?

Thanks for any insight!

These are the most comfortable reusable N95s I’ve found. We reuse until the straps loosen so about 7-14 days and they are $.70-$1 each, cheaper if you set a subscription and get the 50pack .

( I haven’t found a source other than Amazon for that exact model)
