Bead filters are closed (pressure) vessels filled with thousands of plastic beads. These beads are very close together and form a layer through which the water is forced by a pump. As a result, the dirt particles stick in the beads. If the filters are used for some time, the biofilm (the sticky layer) around the beads becomes thicker, so that finer and finer dirt is caught.
