They are designed to capture and remove larger debris and particles from the water as it passes through the filter. The bristles of the brush provide a textured surface that traps leaves, twigs, and other debris, preventing them from entering the deeper layers of the filtration system. By capturing these larger particles, they help prevent clogging in other filter media.
