Boost Oxygen Pocket Size Menthol-Eucalyptus 3 Liter Canister | All-Natural Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (3 Pack)

I Ordered the wrong size but it works good

Often when I do some simple things around the apartment, I get out of breath. I stop, sit still and still feel as though I can't get enough air when I breathe. I have been keeping a pocket size canister nearby and a few deep breaths as directed bring relief quickly. Before I discovered these I would sit for 20 minutes or more feeling terrible. It's a great relief.

product was not what I expected

Good to get additional oxygen when out of breath small easy to carry in purse

Works! I have restrictive lung disease, a side effect of chemotherapy and these canisters help me hike in the mountains and breathe easier while I do it.
