Boost Oxygen95% Pure Aviator's Oxygen- 5 Liters, 3 Pack

I’m not sure what is in this can but it sure isn’t 95% oxygen. A simple test will show this. Light a candle and expel the gas onto the flame. With these cans, the flame is blown out. With an actual cylinder of oxygen, it doesn’t matter how fast the gas blows on the flame, the flame will become more intense with the oxygen blowing on it. Yes, I did this experiment.

I was an active duty medic with 3/75 for 8 years and know the positive effects of H2O (oxygen). You feel invigorated, more alert, etc. Exactly what this seller claims. This is absolutely canned air...better off filling your tires with it.

Despite the label saying that oxygen is weightless - compressed gas will add weight to any canister so when these arrived weighing about the same as an empty can, I did a few experiments.1. the candle/jar test - No change in flame size, color2. oximeter test - No change after inhaling to oxygen uptake levels3. weight of can empty and "supposedly full" - barely negligible4. 100, 1 second inhales. Got as far as 25 over 2 days and then empty5. the somewhat subjective "feeling test" NO difference. I've experienced a distinct difference in oxygen bars.6. emailed manufacturer based on comments here, no response in 6 days.I'm beginning to think this is a potential large scale snake oil type scam!

I got this for my sister, who suffers with COPD. She uses inhaler, but they don't help too much. She often huffs and puffs after coming up her stairs, when walking up hill, etc. A little while after I gave it to her, she called me and was really excited. She had come up the stairs and was gasping, so she tried the Oxygen, and it helped her recover quickly. So, this looks like it is doing exactly what I wanted it for. Happy camper here!

Love using this boost oxygen, but beware of the 5Liter, these are the SMALL cans. 22OZ is the large can.
