Dornking is a showerhead with a filtration function. It filters out tiny impurities and harmful substances such as residual chlorine and rust. Its handle has a switch button, which can conveniently control the consumption of filter material, thereby prolonging the use time of the filter cartridge. At the same time, consumers can conveniently observe whether the filter material has been consumed from the transparent window of the handle to determine whether the filter cartridge needs to be replaced. Moreover, its simplified geometry and concise design make it novel and unique.
