Boost Oxygen Pocket Size Natural 3L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (2 Pack)

I used it for a trip to the Colorado Rockies. At 80+ years, it certainly helped in the oxygen-starved air. These small ones are easy to carry around.

For those with COPD problems or other problems leading to shortness of breath, there is no better way to handle the existing situation than to inhale as deep as possible a breath of Boost and hold it as long as possible before exhaling. Your recovery will come with exhaling, and repeating the process if need be. That’s quick relief! The product comes in a pocket sized can with a properly positioned relief valve for easy release of the oxygen. A quality product of maximum value when one is gasping for air!

I always carry a small size in my bag wherever I go. When I go to the gym, camping, or long trail walks, it gives me a shot of fresh air and replenishes o2 when I need a little Hydration, great taste, perfect size! The price is good for the value.

It was a little expensive for the sizes you get, but it had a very nice scent and was relaxing!

Small, easy to carry around, light, easy to use, does the job, no taste. I got this for my Mom (who has some minor lung issues) to have when she travelled for a few days to altitude 7800ft. She used it a few times after climbing stairs or exertion to regain her O2 levels (we measured with a pulseoximeter). This product served us well.

I accidentally purchased these small canisters of oxygen for my elderly mother. I thought I was purchasing three large canisters. However, these ended up being just what we needed. She now carries one in her purse for emergencies. These small oxygen canisters are very easy to use they have no smell or taste and assist her when she’s struggling to get oxygen in these are absolutely a value for the money and I will continue to purchase them.

Too expensive

I used this product on days with bad air quality. I keep one in my vehicle and one in my golfbag. There is no smell. Oxygen in these cans are orderless and colorless.
