Boost Oxygen Pocket Size Natural 3L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (4 Pack)

The pocket sized Boost oxygen cannisters were perfect when we went on vacation. They fit in my purse so my husband always had his oxygen when he needed it. It is handy when it is hot and humid to help with breathing. You don’t need a prescription because it is not medical oxygen. The Boosters oxygen is for temporarily supplying a little more oxygen for short periods. It comes in different sizes, and I think it is a good value for the price. My husband said it helps him breath deeper and easier ,and he is quite satisfied with this product.

I wish I would have ordered the bigger size. We used all 4 of these within a few days. They did help with some elevation and vascular issues.

I have COPD ( none smoker) and Asthma. With the world weather my lungs this one day my inhaler I didn't feel my inhaler was enough, so I opened the package and read the instructions. Once I felt ok I sprayed 3 shots and boy I haven't felt that good for awhile. The can feels like it doesn't have anything in it. Oh hell it does. I hope I won't need to buy any more but if needed I'm going to feel comfortable buying.

This product is fantastic. It has saved my husband's life several times. If you can't breath, it is scary. This product gives you piece of mind.

I use oxygen at night and sometimes need a little after exertion or while exercising. I carry one of these in my purse and find that it works well when I find myself gasping for air after doing things like getting in the car or going uphill. Usually 4-5 puffs is enough for recovery. I saw a video suggesting that each small cannister holds about 100 puffs.
