Filtration elements are components within a filter that trap contaminants. They function by:

Surface Filtration: Capturing particles on the filter’s surface.
Depth Filtration: Entrapping particles within the filter media.
Adsorption: Attracting and holding particles through molecular forces.
Magnetic Attraction: Using magnetic fields to remove ferrous particles.
Materials used include cellulose, synthetic fibers, metal meshes, and magnets, each tailored to specific contaminants.
