PROBLEM TO BE SOLVED: To suck and remove dust stuck on air filter material to easily regenerate it by constituting the air filter material of mesh base cloth and pile forming a filter layer on the surface of the base cloth and forming the pile of multi- filament crimped yarn consisting of fiber of a specified fiber diameter. SOLUTION: Regenerative air filter material 10 consists of base cloth 10 and pile 3, and into the base cloth 2 woven into a netlike shape in advance, the pile 3 may be woven, or the pile 3 may be woven at the same time when the base cloth 2 is woven, The pile 3 is formed into a brush shape of density and length required as an air filter by using multi-filament crimped yarn which consists of fiber of fiber diameter 10μm-71.7μm and whose bulkiness measured by JIS L 10905.9 bulkiness A method, initial load 0.3 kPa, final load 14.7 kPa is 10 or more. And pile density forming a filter layer is made 40,000 d/in2-570,000 d/in2, and pile length is set within the range of 3 mm-20 mm.
