Abstract: The tube-shaped pleated filter member may comprise: a filter body having a tube shape such that a filter medium is pleated and is wound; and a support unit. The filter body may comprise outer pleated portions corresponding to the outside of the tube shape, and inner pleated portions corresponding to the inside of the tube shape. An inner virtual line connecting corners of the inner pleated portions may have the shape in which a unit wave shape recessed in the outward direction is repeated. Assuming, that the thickness at a part having the maximum distance between the inner virtual line and the outer virtual line is a first thickness (T1), the first thickness (T1) may have a range defined by [equation 1] with regard to the diameter (D) of the outer virtual line. D/15≤T1≤D/6.  [Equation 1]

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.
