Pond One Prefilter Sponge 160x160x450mm PM1300 To 4900

The Pond One Prefilter Sponge 160 × 160 × 450 mm is a large, durable open-cell foam sponge designed for high-capacity pond pumps. It fits over the pump intake to provide effective mechanical pre-filtration, capturing leaves, debris, and coarse waste before it reaches the pump, reducing clogging, maintenance, and extending pump life. Its expansive surface area also encourages beneficial bacteria growth for improved biological filtration, promoting clearer and healthier pond water. Easy to remove and rinse, it’s ideal for large ponds requiring maximum filtration efficiency.
