1. Raw water enters the fixed seat through the water inlet of the B-type fixed seat, and enters the filter from the activated carbon filter water inlet (the center of the top of the filter shell).
2. Raw water enters the raw water channel in the center of the household water purifier filter and passes through the fiber activated carbon + PP composite filter material. During the process of passing through the filter material, activated carbon fibers adsorbed large particles of impurities, organic matter, heavy metals, residual chlorine and other pollutants in the raw water, so that the raw water was purified;
3. Purified water gathers in the space between the outer wall of the filter and the filter shell, and then flows through the water outlet at the top and side of the filter shell to the filter fixed seat water outlet, and flows out from the fixed seat water outlet.
4. The quick-change activated carbon filter for household water purifiers is used in conjunction with the B-type fixed seat, so its water flow mode is internal water inlet mode. The water flow mode is controlled by the fixed seat, which must be considered in the design process of the filter. In special cases, the activated carbon filter can also be used with A-type fixed seat.
