2Pack Adult Non-Rebreather Oxygen Mask with Reservoir Bag - Size L

Hi, we got these for the hyperbaric oxygen therapy chamber we have (for cancer). I needed a rebreather mask, and the adult masks were too big for my face. So we were blessed o find these. Thank God! They fit well, just wash your face for maximum suction (I'm 15 minutes compressing, an hour of full compression, and 10 minutes decompressing). Would recommend. Thank you and God bless

These work. They are a gas

The reservoir bag is just too small. I get about half a breath on it and the off gassing odor is pretty strong
