O2 Blast - Pure Oxygen Supplement, Portable Can Filled with 99.99% Pure Oxygen with Custom Breathing Mask, Energy, Performance, Fast Recovery Time, Ideal for High Altitude & Sports - 10L, 12-Pack

This works great, easy to use. Not a substitute for Oxygen tank. It is helpful

Easy to use Nice have on hand, esp with heart problem. It’s nice to have some O2 on hand to clear my head

As an endurance athlete, I like to take about five deep breaths of O2 before training. I have used BOOST for a long time, but it seemed overpriced, and I have looked for a less expensive alternative. This one is cheaper per bottle, but the number of oxygen hits I get per bottle is far less than with BOOST. My guess is that the cheap packaging allows oxygen to leak out. Bottom line: BOOST costs more per bottle, but it is a far better value, although it is way overpriced.

I have used Boost oxygen for several years....thought I would try Blast to compare. I found that Boost was better.....my reason was the Boost lasted much longer! Seemed not to be as effective. Not a bad product, but think I will stay with Boost.

One can out of the 3 pack worked well and expelled oxygen from the lever. The other 2 cans are sporadic and not effective. I will call for replacement.

I’ve tried O plus, Boost Oxygen, and now O2 Blast. Both of the previous Oxygen supplements had significantly more pressure than the O2 Blast. I think the Optus and Boist provide more oxygen

This seems to help when I'm working in the yard or hiking in the mountains. If I feel tired and out of breath I take three shots of Oxygen and ready to go again. I think this is a good product for high elevations.

ideal for people with breathing problems
