Boost Oxygen Extra-Large Rapid Response 12L Canister, 12 Pack | Our Longest Lasting Can • No Added Aromas • For First Aid Kits & Emergency Preparedness

Works great especially when you're in the mountains at 8000' and have a cold. Really helped. Plus saved some money.

This is a great product! My husband takes between 3 & 6 deep breaths every morning. As a diabetic & pacemaker patient this is a sure BOOST to get him well oxygenated!! I won’t hesitate to use it when I feel I’m needing it.

The problem is you don’t know when it’s empty air still comes out

Goes into my emergency first aid kit. I think having O2 is always a goid thing to have just in case.

Good value!

quick delivery would be nice to know ho much is left?

Works great and last much longer than the other cans. Most other cans, leak out on their own after the first use. So, you can use them once,let it sit a couple of weeks and come back and it’s empty. Not these. They don’t leak down on their own.

I’ve bought this item twice now and both times one can has very little oxygen in it. I liked the fact that they are 12 liter but having one which seems to have leaked out does make me less likely to purchase these again.
