👉 Demo fumes refer to the temporary, often unpleasant odors released during the setup or operation of electronic devices, such as computers, printers, or audio equipment, before they reach their optimal performance. These fumes are typically caused by the heating of components like fans, resistors, and capacitors, which can release volatile organic compounds (VOCs) and other chemicals into the air. While generally harmless in small quantities and dissipating quickly, prolonged exposure to demo fumes can be irritating to the eyes, nose, and throat, and may cause headaches or dizziness. To minimize discomfort, it's advisable to ensure proper ventilation when using these devices.
