Abstract
Disclosed therein is a reverse osmosis water purifier having a simple filter configuration, which includes filter parts consisted of a sediment-filter, a chlorine-resistant polyamide composite membrane and a post-carbon-filter. The reverse osmosis water purifier can be designed in slim size by omitting a pre-carbon-filter, and provide drinking water of good quality since a portion of the residual chlorine in the feed water pass through the chlorine-resistant polyamide composite membrane to the downstream of said membrane and the residual chlorine can inhibit an adventitious growth of microorganism in the post-carbon-filter or the purified-water tank.
