You can buy the 1 litre scuba tank. The cheapest that I can find is Deedepu from Aliexpress. Only RM400 including postage.  I prefer this brand because it is reviewed in Youtube.

At minute 11:06 where he explains that you can get 10 minutes using air using a similar 1 litre tank. You can dive longer if you use pure oxygen provided you do not exceed the maximum depths of 4 m, or 13 feet, except during an emergency for short periods of time of 6m or 20 feet.

At minute 9:55 he explains the maximum depth if you use pure oxygen. For recreational use, you are allowed 1.4 bar partial oxygen pressure which means 4 m. For emergency, you can dive to 6 m.
