The Pond One Prefilter Sponge 120 × 120 × 295 mm is a large, durable open-cell foam prefilter designed for use with Pond One Pondmaster PM1300 to PM4900 pond pumps. Fitted over the pump intake, it provides highly effective mechanical pre-filtration by trapping leaves, debris, and coarse waste before they enter the pump, helping to prevent blockages, reduce maintenance, and extend pump lifespan. Its increased size and surface area also support beneficial bacteria for enhanced biological filtration, contributing to clearer, healthier pond water. Easy to remove and rinse clean, it’s an ideal solution for medium to large pond systems requiring extra filtration capacity.
