About

The character 滤 is a phono-semantic compound. Its semantic component, the water radical 氵, indicates a process involving liquids, while the phonetic component is 慮 (traditional form 濾) or its simplified counterpart 虑. The core meaning of 滤 is to separate suspended particles, impurities, or unwanted substances from a liquid or gas by passing it through a porous material like paper, cloth, or sand. This concept of purification through a permeable barrier applies across a wide range of contexts, from traditional culinary straining of tea or broth to complex modern industrial and chemical filtration processes.
