1. A filter module for a gravity-based water purification device, comprising:
a first support frame and a second support frame, each comprising a loop-shaped edge member having an empty space with a first open surface opposite a second open surface, a compartment member coupled to the edge member and configured to compart the empty space into a plurality of storage spaces, and a communication path in the compartment member, configured to connect the plurality of storage spaces with each other, wherein the first support frame and the second support frame are parallel and spaced apart from each other;
a plurality of filtration members having a plate shape with a certain area and coupled to the first support frame and the second support frame, respectively, configured to produce filtered water from raw water moving from outside the filter module to the plurality of storage spaces;
a common water outlet member configured to integrate filtered water stored in the storage spaces of the first support frame with filtered water stored in the storage spaces of the second support frame:
a water outlet coupled to the common water outlet member and configured to discharge the filtered water to outside the filter module;
a first discharge path in the first support frame configured for the filtered water stored in the storage spaces of the first support frame to move toward the common water outlet member; and
a second discharge path in the second support frame configured for the filtered water stored in the storage spaces of the second support frame to move toward the common water outlet member,
wherein the common water outlet member is between the first support frame and the second support frame, and comprises a flow path for gravity-based flow of the filtered water,
wherein each of the first support frame and the second support frame is respectively fastened through fixing members on a surface of the common water outlet member so that the first discharge path and the second discharge path connect to the flow path, and
wherein the first support frame and the second support frame are spaced apart from each other through the common water outlet member.
