Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that deeply filters and purifies water quality according to the requirements of water use. The water purifiers that are usually mentioned generally refer to small purifiers used for household use. The core of its technology is the filter membrane in the filter element device. At present, the main technologies come from ultrafiltration membrane and RO reverse osmosis membrane. The water purifier can effectively filter out the rust, gravel, colloid and other chemicals in the water, such as residual chlorine, smell, different color and pesticides in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water. The application of water purification technology in the field of drinking water will make the phenomenon of "acclimatization" quickly become history, effectively solving the endemic diseases caused by excessive harmful substances in groundwater in many places.

However, when the water purifier purifies water through the filter element, since the water flow is one-way through the filter element, a large amount of dirt will adhere to the filter element after long-term use, which results in a limited service life of the filter element. It may be inconvenient to replace the filter element.
