The device includes mainly a window frame, a wind drawing pipe and a filter, a fan is also provided to create the above stated negative pressure on an air guiding groove at the circumference of the window frame and the throw-in gate to absorb air with bad odor to filter out dust in the air and do ion exchanging with the filter to eliminate bad odor.
