What is balloon gas?

Modified on Fri, 12 Mar 2021 at 06:30 PM

Helium supplied to the balloon industry is sometimes called balloon gas because it is a mixture of air and helium. The term “balloon gas” distinguishes it from the 99.99 percent ultra-high purity gas used for other purposes such as the medical field.

 You do not have to request "balloon gas" from your helium supplier, as the term is not widely used. Suppliers will know what gas to supply you with.


You may have noticed that different companies have varying gas compositions. BOC (Binary offset carrier) helium gas is typically used to inflate balloons. BOC cylinders are available in a variety of different sizes. The 124CV cylinder is designed with a built-in regulator, which makes it great for smaller events. This cylinder is mixed with 3.0 percent air and 97 percent helium. 


There is an ongoing helium crisis and it is hard to when or if it will come to an end. For this reason, many decorators are incorporating air-filled designs into their events as an alternative. Check out the Bargain Balloons decorating corner for air-fill decorating ideas.


Helium should be respected and used properly. Review our “Helium Safety” article, for details on how to practice proper helium use.
