A filter unit may include an electrode structure, a fluid-purifying flow path, and a pH adjusting chamber. The electrode structure may include a cathode, a cation exchange membrane, an anion exchange membrane, and an anode in that order. The fluid-purifying flow path may be at least one of a path in the cathode, between the cathode and the cation exchange membrane, between the anion exchange membrane and the anode, and in the anode. The fluid-purifying flow path may include an adsorption function. The pH adjusting chamber may be between the cation exchange membrane and the anion exchange membrane. The pH adjusting chamber may be configured to control the pH of the fluid in the fluid-purifying flow path.

A filter unit may include a water permeable first electrode, a second electrode arranged so as to be spaced apart from and opposite to the first electrode, and a non-water permeable separator that is positioned between the first electrode and the second electrode. The first electrode may include a metal adsorbent (metal-adsorbing material) and thus may adsorb a metal included in the water. At least one of the first electrode and the second electrode may induce a water hydrolysis reaction to produce H+ ions to regenerate the metal adsorbent. The filter unit may further include a voltage applier to provide a filter system.
