Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonwoven fabric filter high in the collection effect of pollen or dust, good in air permeability even if impregnated with a drug such as a pollinosis preventing drug or the like and excellent in actual feeling of effect and use feeling. SOLUTION: A nonwoven fabric filter is obtained by arranging hydrophilic fibers and/or hydrophobic fibers on at least the single surface of a hydrophobic nonwoven fabric and integrating them by water jet entanglement and the fineness of the fibers constituting the hydrophobic nonwoven fabric is 5-20 denier.
