A drain filter assembly includes a screen filter that is configured to be installed at a drain and that is configured to block foreign substances in liquid while the liquid passes therethrough. The screen filter includes: a plurality of filter holes configured to allow passage of the liquid into the drain, where each of the plurality of filter holes has a pore size that is less than sizes of the foreign substances; and an air communication hole configured to allow passage of air the liquid passes through the plurality of filter holes. A diameter of the air communication hole is greater than the pore size of each of the plurality of filter holes.
