Abstract:
A method for manufacturing a filter medium for an air filter having improved particle collection performance using cellulose nanofibers. The method for manufacturing a filter medium for an air filter comprises: causing a mixed solution containing cellulose nanofibers and a dispersion medium to adhere to an air-permeable support; and subsequently freeze-drying the resulting product, in which a number average fiber diameter of the cellulose nanofibers is 1 to 50 nm, the dispersion medium is a mixed dispersion medium of water and a water-soluble organic solvent, and a solid content concentration of the cellulose nanofibers in the mixed solution is 0.001 to 0.150% by mass.

Claim (Index 2):
The method for manufacturing a filter medium for an air filter according to  claim 1 , wherein a ratio of the adhesion amount of the cellulose nanofibers with respect to the support is 0.001 to 0.200% by mass.
