The liquid inside an air duster is typically a compressed gas, such as difluoroethane or tetrafluoroethane, which is in liquid form under pressure. When you spray the air duster, the liquid rapidly evaporates into a gas, creating a strong burst of air to blow away dust and debris from electronic devices and other surfaces. It's important to use air dusters in well-ventilated areas and avoid inhaling the vapors, as they can be harmful.
