Air Duster, also known as compressed air or canned air, is a product that is used to clean various types of electronic devices, such as computers, keyboards, and cameras, by blowing air to remove dirt, dust, and other particles. The canister contains a propellant, typically compressed air or a mixture of nitrogen and other gases, that is used to force air out of the nozzle. The product is often used as a cleaning tool in households, offices, and computer repair shops, as well as in industrial settings.
