Abstract: An electrodeionization filter includes: a housing having a water inlet and a water outlet; a first electrode installed inside the housing in a spiral shape; a second electrode installed inside the housing in a spiral shape so as to be spaced apart from the first electrode; and an ion exchange module installed between the first electrode and the second electrode for adsorbing or desorbing ionic substances contained in water introduced by an application of electricity. At least one of the first electrode and the second electrode has a structure in which a center portion thereof is denser than a peripheral region thereof. Accordingly, the lifespan of the electrodes of the electrodeionization filter can be increased, and the assembly of the electrodes and related parts can be easily facilitated.
