After water purification from filter, purified water will enter the cathode chambers and anode chambers of electrolysis system.

At anodes, the ions (OH^-) from water molecules release electron and change back to oxygen (O₂), and hence, the rest ions (H⁺) from water molecules still remain in water to make the water become acidic. The acidic water is discharged via acidic outlet.

At cathodes, the ions (H⁺) from water molecules gain electron and change back to hydrogen (H₂), and hence, the rest ions (OH^-) from water molecules still remain in water to make the water become alkaline. The alkaline water is discharged via the flexible faucet.
