Description

Multi-layer composite filter element

technical field

The utility model relates to a filter core, in particular to a composite filter core.

Background technique

People carefully select the source of water for drinking water, and often carry out some follow-up treatment. For example, people choose wells or springs with better water quality as water sources, and dry and settle the water taken out. Now people tend to carry out more careful treatment of the water taken out to generate tap water.

Although people have carried out multi-channel treatment procedures to drinking water, it still cannot guarantee that drinking water does not contain harmful components. The problem of heavy metal ions, bacteria, microorganisms, and disinfectants in drinking water, as well as the lack of trace elements necessary for human body in drinking water, has attracted more and more attention. People's traditional water treatment methods obviously cannot effectively guarantee that the content of heavy metal ions, bacteria, microorganisms, and disinfectants in drinking water is low enough, nor can it guarantee that drinking water contains trace elements necessary for human body.

The traditional filter element only adopts a single-layer filter structure, which has a low service life and needs to be replaced frequently. Most of the filters are made of iron wire. Iron wire is prone to rust and will also cause harm to the human body.
