At your local oxygen supply.
You will need to determine which tank you have or which tank you will buy:
- 870 Medical oxygen tanks, requires a prescription from your doctor (recommended)
- 540 Industrial oxygen tanks, can be purchased at welding supply, Airgas, or Praxair
We recommend that you buy the oxygen tank locally … even though we sell them. It will save you money.
Oxygen tanks cannot be shipped full, they must be empty. No matter who you buy from.
This means you have to get the oxygen tank filled locally. It usually cost about $100-120 to purchase an oxygen tank and get it filled. It typically cost $20-$30 to get it filled.
We will happily sell you the oxygen tank, but it’s generally cheaper just to purchase locally… plus you still have to take it in to get it filled anyway.
Once you have your oxygen tank, these are your options -

- Welding suppliers
An 870 Medical Oxygen Tank requires a prescription first. Once you have a prescription you can go to a local home-care pharmacy and to get an 870 Medical oxygen tank. Ask for a size between 20-40 cu/ft. An oxygen tank this size will be about 5”x18”. We recommend the 870 tank over the 540.
A 540 Industrial Oxygen Tank does not require a prescription. You can find these at companies such as AirGas or Praxair. Simply request a new tank between 20-40 cu/ft.
Some locations, especially industrial, will make you swap out oxygen tanks. If you do not want to swap, call the location ahead of time and check.
Ask for 99% pure oxygen in your tank from an industrial supplier. Industrial oxygen suppliers will refuse to serve you if you are using it for a medical purpose.
Tanks come in all sizes, you can get as small or large as you want.
