Boost Oxygen Pocket Size Natural 3L Canister, 4 Pack | Ultra portable canisters that can fit anywhere | No added aromas | Perfect for on-the-go quick trips

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 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.

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.

These tanks are excellent for athletes, people that are hiking and higher elevations they just need a deeper breath, or the people with health conditions like my mom. She was able to sustain her oxygen level while waiting on her intigen oxygen pump to charge up.

i bought these as a precaution for our long weekend at a high altitude mountain resort. I am a 67 yr old grandma and hiking was never something i loved but i endured to keep up with my family… these small canisters of oxygen REALLY helped me and other family members. I will definitely buy these again!
