Boost Oxygen 5 Liter Natural Pure Canned Supplemental Oxygen Bottle with Built in Mouthpiece for High Altitudes and Recovery, Natural Flavor (5 Pack)

The canisters aren’t always full . They do work for a short fix.

I have copd and use these when I need them.

Easy to use. Great if you need a quick puff of air.

The order came today, it was one day after posted arrival date…not a big deal. The cans were clinging around in the box, a little packing paper is needed. Other than that, thank you very much for getting the Boost oxygen to me I would be a good influencer for this product. Jason Cowan

A pulmonary therapist was pleased to hear we had purchased this product for travels above 4K feet altitude. It is not a continuous feed of oxygen- but consecutive bursts of oxygen are perfect for short term use. Pleased with this option, highly recommend.
