When it comes to flying, the airlines think of every possible way to not waste anything, and that goes for the air that you breathe in the cabin. Almost everything on the plane is recycled, and the air that you breathe actually comes from the engines of the aircraft. The engines intake the air, which is then recycled and filtered, so it is suitable for humans to breathe.

Many people have questioned if the quality of air on planes is actually good, and several scientists believe that there are dangerous chemicals that are not being filtered out. Hopefully, this is something that will be looked into more thoroughly as time goes on.
