Boost Oxygen Medium Natural 5L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (2 Pack)

work great!

Very handy and effective in a pinch. I keep a can in my back pack when hunting Deer and Elk. Helps give a quick boost when packing a load in the mountains. My wife got sick and Her O2 levels were down in the mid eighties. That is NOT GOOD. I gave her a can of this O2 and it brought her levels back into the nineties quickly. I was very glad to have that on hand at that moment!

Works great but a little expensive otherwise would give it a five

Really nice if you need it. Will increase your stats at least to 95 with three puffs, however does not replace o2 therapy. It's temporary for athletes and to that end shouldn't be used as therapy. It is however a temp solution until you can replace you regular o2 supply, do not think it can replace that 3 puffs replace o2 to 95. For a short while.

I purchased the Boost Oxygen Medium Natural 5L Canister 4-Pack mainly for post-workout recovery and high-altitude trips, and it's definitely made a difference. Each canister is lightweight and easy to use, with a simple push-button spray that delivers a quick shot of oxygen when I need it most. I’ve used it after intense cardio sessions and noticed quicker recovery and less fatigue. It’s also been a lifesaver during hikes at higher elevations—helped with breathing and kept headaches at bay. The natural, unscented option is a plus if you're sensitive to smells. The only downside is that the cans don’t last super long if you're using them frequently, but for a short-term boost, they do the job well. Definitely recommend keeping a can or two on hand for travel, training, or just general wellness.

I am a senior and I bring one to therapy while I am recuperating from wrist surgery. When it gets hard on me with the pain I did a breathe. It seems to help me get through the pain or no gain.

I'm a very big & tall guy (6' 9" & 220 lbs), & have spent the better part of 25+ years exercising (both wt. lifting & aerobics), all the while struggling with lung & O2 issues I've had since birth; meaning that no matter how much cardio I do, I will still fall short of those without this condition. I've used O2 tanks (the heavy / hospital variety) & have been on steroidal inhalers to help increase my O2 when exercising, & each of these methods have proven quite effective in maintaining my endurance along-side those who don't have this condition. This said, the prospect of an ultralight O2 delivery method was quite appealing (even over the inhaler). Alas, it's all smoke & mirrors. For those who swear by this product, I'd also like to mention that in hundreds of thousands of case studies, where a placebo was used, the placebo would occasionally perform just as well as the controlled product; e.g. "mind over matter". In my case, since I have a REAL O2 delivery system (e.g. the med-ox regulator), I can compare how it works to this product. Even when using a foam seal (made from pipe insulator) to help "seal" the rim of this product around my mouth, I feel no different than when I breathe without it. By contrast, after running for 30m< &/or huffing & puffing during &/or after an intense cardio workout, both my "O2 tank" & inhaler offer me near-instant O2 relief (with the O2 tank offering my more "satisfactory relief", faster; hence why this product seemed more appealing than my inhaler). Add to this that when I check my pulse oximeter after an intense workout & use my tank or inhaler, my O2 levels out (to normal) pretty fast. My O2 didn't increase OR level out with this product, but rather decreased (I think b/c it is NOT "pure oxygen", & by putting it on my face, thus restricting my high-volume breathing, actually decreased my uptake). In short, if this works for ya... great. But for those looking for a REAL O2 boost, I'd say stick to O2-restrictive masks (e.g. build your endurance the long & steady, but true, way); adjust your diet to accommodate better red blood cell creation &/or O2 uptake; look up breathing exercises; consider a small, light-weight (1< lb, 25 LPM) O2 tank, to use during or after an intense workout as "recovery O2"; &/or talk to your doc about how to boost your blood O2 (especially if you have O2 medical conditions; like me). The take away..............................? It's a nice concept, but ridiculously fails, as it is NOT "95% pure O2", like the manufacturer claims. In a nutshell, you are spending $10+ for a nice-looking, brushed aluminum can... filled with the same level of O2 you can get by stepping outside. For all intents & purposes, you could take a large garbage bag & "capture" the outside air & breathe from that while working out to get the same effect as breathing from this can (for my own "control test", I actually tried this, lol; & both my pulse oximeter & O2 gas detector reflected this result as well ~ just as other reviewers have stated / shown w/ pics).

We are using them to escape the house in case of a fire. As a 30 year firefighter, I saw more people die from smoke inhalation. I gave only three stars because they are pure oxygen and not just compressed air. O2 can explode in a fire.

رائع جدا

Muchas gracias. Llegó en muy buenas condiciones. Llegó antes de la flecha señalada. Excelente. 👍🏼

Easy to use and just what was wanted. Very effective.

Ich bekam Atemprobleme. Würde ich nicht noch einmal kaufen.

I use this a couple of times a day, one big breath each time. Definitely helped post covid and with clearing air pollution.
