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

Why did you pick this product vs others?:Purchased for family member with broncal issues who regularly has trouble breathing and maintaining oxygen. This has been an amazing support. Almost better than the inhaler. They are now a staple. I just wish they could be slightly cheaper to maintain a regular subscription. Or, be covered in medical insurance. Tremendous difference in mobility following use by the senior it was purchased for. Clears his lungs better that the inhaler and without jittery side effects. Just wish it were more affordable in bulk.

My father has been diagnosed with Pulmonary fibrosis, it's not server yet but his insurance hasn't kicked in for Oxygen tanks. Bought this as a substitute for now and it's been a great help. Where he'd be out of breath and difficult for him to walk he's able to recoup himself fairly quickly with this. We've now bought multiple and keep them everywhere in case of an episode.

This product is easy to use and it gives a quick boost of oxygen after a strenuous activity. Have used this for several years and just want to have it on hand when needed.

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.

My husband has COPD and these work great for him when he is experiencing shortness of breath. Two quick shots and he is usually feeling better right away. The product has no taste or smell and the can feel like there is nothing in them, but I assure you its in there. The only problem is that you cant feel when its almost empty because it already feels that way. Maybe a shot counter or a level gauge to tell when its almost empty. He doesn't like it when he reaches for it and it empty.

It does help if you only need 6- 7 blasts of actual oxygen. After that it's just compressed air

This product works fine for when carrying an oxygen tank is difficult.. Put it in your picket or purse for use when you're away from home.

I use it when I feel out of breath and it works very well. The quality is good.
