The utility model relates to a long-acting type filter water purifier, water supply pipeline is connected to the tap water, including ultrafiltration membrane assembly, water solenoid valve, a booster pump, a reverse osmosis membrane, one-way valve, activated carbon, water pressure proportioner, storage tank, pressure switch, activated carbon and water tap. The utility model overcomes the shortcomings of the existing drinking machine can produce a large amount of waste water, waste water, using activated carbon filtration device post, reduce the activated carbon filter load, improve the service life of the active carbon, so the replacement cycle of the activated carbon increased, reduce the cost. At the same time, the ultra filtration membrane component is directly installed on the tap water pipeline, and the living tap is directly used, and the ultrafiltration membrane can be cleaned at any time while the water is used at ordinary times.
