Hello, is there a place in Suzhou where we can rent oxygen cylinders for home use? I'm not sure if you're going to be able to find a way to do that.

It depends on how long you use it, if it's a few months, it's still a good deal, if it's more than a year, it's recommended to just buy a new one. You can start by finding a distributor that sells industrial oxygen, they usually have oxygen cylinders. There is not much difference between the medical and industrial ones. The main thing is that the medical must keep the bottle clean can not enter the impurities, air, etc., so as not to affect the purity of oxygen.
