Electronic water treatment and filtration with an electronic, self-cleaning filter function, mainly by the housing, water movement, the controlled device, cartridge, clean the motor, clean body and electric butterfly valve and so on. Work, the water into the electronic water through the water after the first movement, in the role of high-frequency alternating electromagnetic field, the set can be activated water molecules, can prevent scale formation, and can destroy the old dirt, bacteria and algae. The treated water then flows through the cartridge, cartridge which was trapped dirt down, when the dirt build-up rises, will plug the filter, the cartridge flow area smaller and smaller, resulting in water flowing through the cartridge increasing the pressure difference before and after. When the pressure difference value to the controller allows
