This creation provides a kind of air cleaner, including a shell, a filter device, an air supply device and a sterilizing unit. The shell has an entrance and an outlet. The filter device sets the what inlet. The air supply device is set in the what shell, which drives air from the entrance toward the output flow. The sterilizing unit includes a plate body and a UV lamp pipe, which sets the what shell, which can be between mobile one open position of what of the shell and an entire position of lid. Thereby, the air cleaner of this creation may filter that and remove the impurity such as the dust in air and bacterium. In addition, the plate body system can be raised outward, therefore user can wipe or replace easily the UV lamp pipe.本創作提供一種空氣濾清器，包括一殼體、一過濾裝置、一送風裝置與一殺菌裝置。該殼體具有一入口與一出口。該過濾裝置設於該入口處。該送風裝置設於該殼體內，該送風裝置係驅使空氣由該入口往該出口流動。該殺菌裝置包含一板體與一UV燈管，該板體設於該殼體，該板體可相對該殼體移動於一開啟位置與一蓋闔位置之間。藉此，本創作之空氣濾清器可過濾並清除空氣中之粉塵等雜質以及細菌。此外，該板體係可被往外掀開，故使用者能輕易地擦拭或更換該UV燈管。
