    Abstract: Proposed is a non-electric water purifier in which a flow path provided between a water-purifying filter and a water outlet cock is replaced in order to minimize contamination of purified drinking water. The non-electric water purifier includes a main body having a door formed on one side thereof so as to open and close the main body and having and having a receiving space part defined therein, a connector which is coupled replaceably and rotatably to one side of the main body and incudes a raw water passage connected to a raw water inlet and a purified water passage through which purified water flows, at least one filter housing being received in the receiving space part, with a discharge outlet of the filter housing being coupled detachably to the connector, and the water outlet cock which is connected to a discharge opening of the connector and discharges purified water.

    Abstract: Disclosed is a reverse osmosis membrane filter for increasing a recovery rate of purified water by extending a residence time of raw water on a reverse osmosis sheet. The reverse osmosis membrane filter having a fluid channel formed on a side surface thereof, according to the present invention, comprises: a central tube having a purified water inflow hole radially formed therein; a guide tube that is coupled to the outside of the central tube and has a raw water moving passage formed in the longitudinal direction thereof and a raw water outflow hole radially formed therein which communicates with the raw water moving passage; a reverse osmosis membrane sheet that filters a foreign substance contained in raw water and supplies the filtered purified water into the central tube through the purified water inflow hole; and a filter housing that accommodates the reverse osmosis membrane sheet.
