About
The character 滤 is a phono-semantic compound: the radical 氵 (water) on the left signals a process involving liquids, while the component 虑 on the right gives the sound. This is the simplified form of 濾, which used the traditional phonetic 慮. The main meaning is filtration, the mechanical act of passing a liquid or gas through a porous material, like paper, cloth, or sand, to trap and remove solid particles and impurities. This concept extends from everyday practices such as straining tea or broth to sophisticated industrial and chemical filtration processes, always emphasizing purification through a permeable barrier.
