Abstract

A portable water-purifying pouch is provided that includes a pouch-shaped body comprising an inlet part, through which water to be treated is introduced, and an outlet part, from which drinking water obtained by filtering the water being treated is discharged and a pouch-shaped filter medium, which is provided inside the body so as to hold and filter the water being treated, which has been introduced into the body, and comprises a fiber web layer having the structure of a three-dimensional network formed of nanofibers. The portable water-purifying pouch allows a large flow rate of drinking water to be obtained in a short time while filtering, with significantly superior efficiency, foreign substances such as bacteria and harmful germs in the water being treated merely by self-weight or by lightly applying pressure with a hand to the water being treated.
