Filter paper is a porous material used to separate solids from liquids or gases. It is commonly made from cellulose fibers and comes in various thicknesses and pore sizes, allowing it to filter different types of substances. In laboratories, filter paper is often used in processes like filtration to purify solutions or collect precipitates. In addition to laboratory use, filter paper is also found in everyday products, such as coffee filters and tea bags. Its ability to trap particles while allowing liquids to pass through makes it an essential tool in both scientific and culinary applications.
