Why do you want to install a pre-filter? What is the function of the pre-filter?

Because the pre-filter is the first coarse filtration equipment for the whole house water, it can filter the sediment, rust and eggs in tap water. Large particles like red worms. The pre-filter is generally installed at the front end of the pipeline, so it is named after the word "pre-filter"; And "filtering" refers to the basic principle of this kind of equipment.

Main functions:

Filter sediment, rust and large particles in tap water. To prevent a large number of precipitated impurities generated in the water supply network of cities and communities from causing harm to human bodies, and to play an active pre-protection role for water appliances (water purifiers, water purifiers, water softeners) such as concealed pipes, faucets, water heating, water heaters, boilers, washing machines, dishwashers and coffee machines.

Application field:

The pre-filter is generally installed behind the water meter, and its main function is to restore the tap water to the standard before leaving the factory and protect the downstream equipment.

Urban water supply pipeline is old and long, and impurities such as corrosion and sediment in the pipeline will not only lead to the control failure of brown water and water-using equipment, such as dripping water from tap (the pressure reducing valves in the market are all in parallel, and the valve core of the tap is ceramic grinding type, and fine particles will make the pressure reducing valve fail in a short time, leading to dripping water from the grinding ceramic valve core), but also the impurities will precipitate on the pipeline;

On the one hand, it provides a breeding ground for bacteria, on the other hand, it will form electrical compounds, which will cause corrosion or perforation of metal pipes in just a few months. The filtering accuracy of the pre-filter is 5- 100 micron, which can filter impurities visible to the naked eye, such as sediment, rust, floating objects, etc., greatly prolonging the service life of the subsequent equipment;

Such as faucets, showers, washing machines, water heaters and toilets. In Germany, pre-filter legislation stipulates that all buildings after 1988 must be equipped with pre-filters, so pre-filters are widely used in European and American markets.
