Boost Oxygen Extra-Large Rapid Response 12L Canister, 2 Pack

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

I purchased these for my 84 year old mom who was taking a road trip with my sister to visit family in Colorado. She was nervous about the elevation and less oxygen so I purchased these more for her peace of mind than anything - however, she actually did use them every so often. She said it helped. Having said that, the cans arrive and feel completely empty. - Oxygen has no weight. A little un-nervey at first. The top of the can has a type of 'mask' you can hold to your mouth while easily pressing on the 'trigger.' Oxygen delivered. Breath deeply and slowly. She believes it really helped just using it every now and then. I have to believe her. The ad states there are about 225 breaths in each can. I purchased this brand as it seemed the best reviewed, the most breaths per can and the shape of the top. Ease of use was important too. I would feel comfortable purchasing this brand again.

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

This cans of pure oxygen have really saved my life. I dont remember what I did before I started using them . Anyone who has a chance of having breathing issue or heavy in sports can use these and once you have tried it . Its just amazing that you can feel better in a matter of minutes.

Came in handy for the wife on a trip to Colorado and the Grand Canyon. It is just weird. The can weighs next to nothing but is full of oxygen.

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

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

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.
