On the other hand, in the water purifier cartridge 6, the lower opening of the outer chamber 6A of the casing 61, which has a double chamber structure with partition walls, serves as the raw water intake port 65, and the lower opening of the inner chamber 6B serves as the clean water outlet port 64. The outer chamber 6A is filled with a first filter 62 such as activated carbon, and the inner chamber 6B is filled with a second filter 63 made of a polyethylene hollow fiber membrane, and the upper and lower parts of the first filter 62 are covered. like,
Each is provided with a third filter 66 such as a non-woven fabric.

Lower wall portion 1 which constitutes the raw water take-out channel C
A connection pipe 8 is provided at a portion of b that faces the mounting hole 7, and the water purification outlet 64 of the water purification cartridge 6 is connected in a watertight manner when the water purification cartridge 6 is mounted. The water purification faucet 9 is rotatably provided on the downward protruding portion 81. That is, the base pipe 91 side of the water purification faucet 9 is connected to the connecting pipe 8 via a plurality of sealing members 92.
