Filters are precision separation devices that function as intelligent sieves in fluid systems. Using specialized media with calibrated pore sizes—including mesh, fabric, membranes, and porous materials—these systems physically capture unwanted particles, contaminants, and microorganisms as liquids or gases pass through. This fundamental process enables critical fluid purification, substance separation, and material recovery operations across countless applications. The filtration rating or precision determines the smallest particle size effectively removed, making proper specification essential.
