Such canisters are ideal for inflating balloons for small parties, school events, and other occasions. While disposable helium canisters serve as a lightweight single-use option for mobile helium supply needs, these canisters serve a dual purpose as portable storage units as well. The helium within the canisters is high quality, ensuring adequate floating ability. All that’s required is to connect the canister to the balloon, and it will soon be ready for use. Once the helium is emptied, side vented canisters can be disposed of freely without needing the permission of local authorities.
