The first thing you need to do is see a pulmonologist and find out if supplemental O2 is in your future. IIf so, in order for insurance to cover any kind of unit, portable or home, you need to pass (actually fail) a walking test. You walk for 6 minutes monitoring…
If your not a candidate for supplementary O2, and just want that boost, Amazon sells breathable 90% O2 in a can called "BOOST". Costa about $10 a can.
I just ordered a 3-pack of 10 liter size Boost from Amazon. $45, so it’s skyrocketed. Like everything else.
