The price of UDF filter cartridge is generally between 50 and 200, and the specific price depends on what brand you choose.

The UDF cartridge is filled in a plastic housing container without any chemical additives. At the upper and lower entrances and exits of the container, there will be multiple layers of microfiber non-woven fabric to prevent the release of carbon powder. The shell is produced by ultrasonic welding process of ABS material. Because the liquid in the water purifier is from bottom to top, the liquid is in contact with the activated carbon particle layer for a long time and a wide area, so it can effectively play the functions of dechlorination, deodorization and deodorization. The activated carbon filter element loads the required activated carbon particles into a special plastic shell, welds the end cap to the two ends of the shell with welding equipment, and puts the non-woven filter sheet that plays a filtering role at both ends of the shell to ensure that the carbon core will not drop carbon powder and black water when used. Depending on the requirements, the housing end cap can be made into different types of connection ports.

The main performance of the UDF filter element is adsorption, which is related to the pore structure of the activated carbon. The specific surface area and specific volume of the micropores are large. Therefore, micropores largely determine the adsorption capacity of activated carbon. On the surface of solid activated carbon, there are two main ways of adsorption, namely physical adsorption and chemical adsorption. Physical adsorption can form multimolecular layer adsorption, which can effectively adsorb organic pollutants in wastewater and waste gas. When an adsorbate comes into contact with the surface of an adsorbent, whether physical or chemical adsorption occurs depends on the surface activity of the adsorbent, the nature of the adsorbate, temperature, and other factors.
