Filter saver socks for your skimmer basket catch small debris that would otherwise contribute to clogging up your pump or filter. An elastic band holds them tight on the edge and catches things such as pine needles, pollen, and remnants from flowering trees, shrubs and small insects.
Sold in packs of 5. Filter saver skimmer socks are made of nylon and fit all size skimmer baskets. They can generally be used for a few months under normal conditions.
