Zusammenfassung:Disclosed is a filtration structure (1), which comprises a mask body (10) and a wrinkle layer (20), wherein the wrinkle layer (20) is provided with a plurality of wrinkles (210) and is arranged on the mask body (10). The superficial area of the wrinkle layer (20) is greater than that of the mask body (10), so that the filtration area of the filtration structure (1) is increased effectively, thereby improving the filtration effect of the filtration structure (1) and improving the air permeability of the filtration structure (1).
