Can't seem to find any good info on this. When I clean out my chicken coop I wear a regular dust mask for 30 minutes or so. It always seems to put me into a very calm, zen-like state. Wondering how much it might be increasing my CO2. This could easily be done on and off throughout the day instead of bag breathing?
