Boost OxygenLarge Natural 10 Liter Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (4 Pack)

Ordered for my wife. It has helped increase her O2 level as we had hoped. The product arrived quickly. Local pharmacies indicated that they carried the product but after visiting four different ones I ordered thru Amazon.

This is very useful and convenient to have when you need a boost of oxygen

Bought these for someone that has respiratory issues and with the recent wildfire smoke coming in from Canada they found these help alleviate the coughing. By no means is this a substitution for seeking medical advice, nor is it a recuse but a temporary solution.These canister are light weight and simple to use. Having tried it a couple of times myself from being outside too long, seems simple enough. One second inhalation through the mouth, no taste nor smell and buying the 4pack seems worth the value. A family of four could each use their own canister when needed.

My wife has COPD , not nearly bad enough to be on oxygen but sometimes, so I brought this with us on a trip into the mountains. Lightweight O2 available if a little extra boost required. We tested it before leaving. Keep a couple in the truck on trips. You never know.

I have used boost for hunting, fishing and camping trips for sometime. If you are at high altitude it's a good thing to have with you to avoid altitude sickness.

I use these to boost my workout at the gym. I usually do a couple of puffs between sets. They really seem to give me more endurance. If you are trying to lose weight and workout or walk, these might help you with endurance. Very much worth it for me.

Great product

This product does nothing for you. It is not even comparable to clean air. Save your money this is not anywhere near pure oxygen. First tip off is the thin aluminum can it comes in. Oxygen is a volatile gas.
