Dust-Off air duster primarily contains a propellant known as difluoroethane (1,1-difluoroethane, or HFC-152a). This is a colorless, compressed gas that is used to create the high-pressure air burst needed to remove dust and debris from surfaces. It's important to use it in well-ventilated areas and avoid inhalation, as it can be harmful if misused.
