O+ Biggi – Single Canister – 11 Liters, 220+ Breaths Per Canister

Not what I expected but it is ok

Fresh Air

I take some meds that sometimes lower my blood oxygen levels. The Biggi Oxygen canister I purchased has worked well for me. It helps to bring up my sats.

O2 OK

4 low o2 when my battery dies on my portable. When going 2 higher altitude.
