Sock Filters

Use sock filters to trap and remove particles of a specific size and larger from liquids. For information about particle size, see About Filters and Particle Sizes. Felt and fabric filter bags have high debris-holding capacity. They trap particles throughout the thickness of the material, which prevents clogs and pressure drops. Fabric filter bags hold more debris than felt bags. Mesh filter bags are often used as the first stage of filtration and to strain small batches of liquids. They trap particles on the surface of the material.
