Zusammenfassung: | A filter media is provided. The filter media includes a meltblown nonwoven fabric, a thermo bonded nonwoven fabric, and a cladding layer. The melt blown nonwoven fabric includes a plurality of meltblown fibers intersected with each other and the basis weight of the meltblown nonwoven fabric is between 25 g/m 2and 85 g/m 2. The thermo bonded nonwoven fabric includes a plurality of staple fibers intersected with each other, wherein a portion of the meltblown fibers and a portion of the staple fibers are adhered to each other, and the basis weight of the thermo bonded nonwoven fabric is between 65 g/m 2and 85 g/m 2. The cladding layer coats each meltblown fiber and each staple fiber, wherein the material of the cladding layer includes polysilazane perfluoropolyethers and the weight of the cladding layer is 5% to 10% of the total weight of the meltblown nonwoven fabric and the thermo bonded nonwoven fabric. |
