Boost Oxygen Pocket Size Natural 3L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (1 Pack)

These little cans of air are awesome. I bought these for a friend who uses oxygen. Sometimes he just needs a small boost of oxygen and these are so easy to use. It allows him to get as much air as he needs. He likes these so much, I have them on auto ship. They arrive in two days and are amazing.

Given that the local area is in a high altitude zone, I keep these on stock in various locations within my home. The mouth piece fits comfortably and makes it easy to use. The inhale of oxygen feels clean and it does not have any sort of foul smell or taste. The compact size makes it easy to travel with as well.

My daughter has epilepsy and these are a game changer after she has an episode. I don't have to wait for police or paramedics .

This product essentially works on the Coandă effect and Bernoulli’s principle. When you press the lever, air shoots out of the canister in a small, fast stream. This creates a sort of pressure vacuum that pulls a lot of air from OUTSIDE the canister, through the gap underneath the lever, into your lungs. To you, it feels like a huge breath of air--because it is--but most of that air is not the pressurized O2 from the canister. Most of it is the same air you were already breathing.If you'd like to test this, light incense (or light a candle and blow it out, to fill the air with smoke). Put the canister nearby, create the seal around your lips as the product directs, press the lever down, and breath in. You'll get a lungful of smoke.I used a plastic bag and duct tape to create a seal around the lever, preventing any outside air from getting in. The difference was stark. I was able to take a TOTAL of three shallow breaths before the entire canister was empty. I noticed no difference whatsoever in the quality of the supposed O2, except that it tasted vaguely stale and chemical.You don't need to do any experiment to conclude all this, by the way. It's pretty simple math. The tiny canisters contain three liters of O2, which they claim is sufficient for 60 one-second breaths. The average lung capacity of an adult is six liters--2x one canister.This product is crap.

The three cans are great to have and keep one in your gym, one in the kitchen and so on. The cans are cute and small but I'm not sure if the three combined equal one regular can. Seems like the regular can has more puffs. For convenience though it's great.

I bought this product based upon the tv ads and know of someone who used a pure oxygen tank as part of their therapy after lung repair surgery. The effects on their body and skin was pretty amazing. Yes, they were using medical grade oxygen, but this should produce similar results when used properly. That's where my review comes in. I took 3 one second hits of this stuff and was lightheaded for quite a few hours. I actually had to lay down for a couple of those hours because of a headache that it caused. It turns out that pressurized oxygen can potentially cause hyperoxia (sp?) and/or oxygen poisoning if not used properly. The instructions are very simple, which makes the product easy to use, but there are no warning labels at all on the product. Warning labels need to exist on all products that make health related claims and pump pressurized anything into your lungs or body. There is risk involved. My guess it that without a warning label, these guys might see a lawsuit at some point. I've emailed directly with them and they seem like great folks with the best of intentions. I just hope they do things the right way here.

These help alot. My husband gets short of air at times, these are a lifesaver. Helps him out of shortness of breath episodes. Easy to use.

Great product, it’s easy to use and increases energy levels. It smell like nothing. It also is easy to use, it will keep emitting O2 until you let go. It shipped fast and got here quick. Thanks
