The invention discloses a filter screen. The filter screen comprises a frame; at least 6 layers of a net structure are fixedly arranged in the frame; from inside to outside, a metal wire net support layer, a porous fibre layer, an active carbon layer, a catalyst layer, a porous fibre layer, and a metal wire net support layer are overlapped on the net structure successively from inside to outside; the catalyst later is composed of a powdery catalyst comprising a carrier, an active component, and a catalyst promoter.
