| description | An air filter material includes a laminate of an air inlet layer and an air outlet layer, and has a mean flow pore size of 20 mum to 40 mum, a minimum pore size of 2.4 mum to 3.8 mum, and a maximum pore size of 80 mum or less. The air inlet layer is a needle punched nonwoven fabric layer having an areal fiber weight of 55 g/m2 to 100 g/m2. The air outlet layer is a laminated spunlace nonwoven fabric made by laminating at least two or more spunlace nonwoven fabric layers having an areal fiber weight of 20 g/m2 to 60 g/m2, a mean flow pore size of 50 mum to 90 mum, a minimum pore size of 3.0 mum to 10.0 mum, and a maximum pore size of 180 mum or less. |
