Formaldehyde is one of the main sources of indoor air pollution, and the removal effect of formaldehyde of common indoor air purification methods such as placing activated carbon bags or green plants and opening windows for ventilation is not ideal. This paper introduces an active indoor formaldehyde purification device that uses a motor to form the air convection and thus purify the polluted air twice. The multiple activated carbon tubes on the device increase the contact area between the activated carbon and polluted air thereby improve the purification efficiency. The experimental detection has proven that the active indoor formaldehyde purification device has a much better formaldehyde removal effect than ordinary activated carbon products, and has high practical value.
