A compact, high flow rate reverse osmosis water filtration system (10) suitable for home use has four primary operating components: a carbon sediment pre-filter assembly (22), a reverse osmosis filter assembly (24), a granulated activated carbon post-filter assembly (26), and a flow controller (28). These four components (22, 24, 26, 28) are operatively interconnected by lengths of flexible tubing (154, 162, 172, 182) provided with finger operable quick disconnect fittings (160, 170, 180, 190) which permit each element to be rapidly disconnected from and reconnected to the balance of the system without the use of tools of any sort. Each of the three filter assemblies (22, 24, 26) is of a throw-away construction comprising a filter material permanently sealed within a housing structure. Filter changeout is thus easily and quickly achieved by the homeowner simply by disconnecting the particular filter assembly and discarding it, housing and all, and then quickly reconnecting a replacement filter assembly in the system. A specially designed combination water supply/rinse water discharge fitting is utilized to operatively connect the system to a sink faucet, and a high purified drinking water production rate is achieved utilizing a rolled, double wrapped filter membrane structure in the reverse osmosis filter assembly (24). |
