PURPOSE: A cartridge filter including a photocatalyst-coated ceramic filter and an adsorbent-packed cartridge for water dispenser is provided. CONSTITUTION: The cartridge filter includes a ceramic filtering layer(1), a supporter(5), a separation membrane(6) and a water outlet(8). On the supporter(5), zeolite layer(3) and elvan layer(4) are formed, and between them interfacial separation membrane(6) is placed. Above the elvan layer(4), activated carbon layer(2) and filtration layer(1) are serially covered by a thickness of 8-15 mm. At the substantially center part of two bottom layers(3,4), a water outlet(8) covered with a membrane(9) of fine pores is vertically installed. Water is gradually filtered through the upper, lower and center parts and finally discharged through the water outlet(8).
