PROBLEM TO BE SOLVED: To provide a cartridge for a water purifier capable of keeping a performance for adsorbing and removing a heavy metal and the like for a long time, retaining an antibacterial performance, and moreover, simplifying the charging operation of an adsorbent into the cartridge and the assembly operation of the cartridge. SOLUTION: A filter material housed in the cartridge for the water purifier comprises the adsorbent which can adsorb an organic matter in raw water and an ion-exchanger which can adsorb the heavy metals in the raw water. The adsorbent comprises an antibacterial adsorbent supporting an antibacterial agent which has the antibacterial performance and a non-antibacterial adsorbent supporting no antibacterial agent. The antibacterial adsorbent, non-antibacterial adsorbent, and ion-exchanger are mixed and charged into the cartridge with the mixing ratio of 20 to 35:60 to 75:2 to 6 in weight% in this order.
