Boost Oxygen Medium Peppermint 5 Liter Canister | All-Natural Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (2 Pack)

Not a treatment for sleep apnea, but I keep it by my bed for when I wake up gasping for air! Take a few breaths before bed and exercising

Great product for an oxygen burst. It's a nice size to have around the house or would fit in a backpack. Delivery took longer than my normal Prime orders so give time for shipping.

I bought these they don't help me a lot like some of the reviews but I'm sure it depends on what you use them for maybe better for people who climb mountains.

These canisters are so handy! And I feel lots better having them around in case I need a shot in a hurry. When the package came it was so light. Of course it is -- air is weightless! There are 5 liters in each canister, which is about 100 1-second inhalations. I like the mouth shield of this brand instead of spraying towards the mouth and waste occurs.

I get cluster headaches. Over the counter headache medicine does nothing (not motrin, not advil, not aleve, not Tylenol, and not even the max strength excedrine). Ice packs are helpful, but they often are too stiff to hold against the spots that hurt the most. Sumatriptan makes me physically sick. So I've just suffered through. I bought these a couple weeks ago and hadn't had a cluster since to try it out, until last night. I was so desperate to end my cluster headache last night that I tried the Sumatriptan again, hopeful that the sickness I felt the first time was a fluke. It wasn't. And my cluster persisted. Then I remembered I had this product. I took 5 deep inhales and magically the cluster headache was gone! Will definitely be buying more of these!
