Medium Focus Rosemary Aroma 5L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (6 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

Boost Oxygen works great.

Great product to keep in medicine cabinet. It really give a great boost.

this time very poor not alot of oxygen in canister.

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.

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.

Este producto es una castaña no sirve para nada
