摘要： 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.

摘要： A side-flow type RO filter is provided including a filter housing including a top-open housing and a bottom-open cap coupled to an opening of the housing, where a raw water inlet port, a purified water outlet port and a concentrated water outlet port are formed in the filter housing; an RO filter provided inside the filter housing with a reverse osmosis membrane sheet wound in a roll-type; and a central pipe provided in a center portion of the RO filter and an exit thereof is connected to the purified water outlet port, the central pipe being configured to collect the purified water that passes a peneratrion hole after being purified by the reverse osmosis membrane sheet and transfer the purified water to the purified water outlet port, wherein the RO filter is configured to transfer the raw water introduced through an outside end of the reverse osmosis membrane sheet in a longitudinal direction of the reverse osmosis membrane sheet thereby extending the transfer path of the raw water and separate the raw water into purified water that passes the reverse osmosis membrane sheet and concentrated water filtered by the reverse osmosis membrane sheet to be transferred to the concentrated water outlet port.
