Abstract
An air filter device is installed on an exhaust device. The air filter device includes a filter net and one or more ultraviolet light-emitting diodes (UV LEDs). The filter net is disposed at an air passageway of the exhaust device. The UV LED is disposed on the exhaust device and located at one side of the filter net to irradiate UV light toward the filter net, hence accomplishing filtering and sterilizing effects to the air passing through the exhaust device and thus improving the quality of indoor air.
