Description: Keep your pool clean and safe with our high-quality swimming pool filter. Made of ultra-fine mesh and durable elastic material, these filters easily capture leaves, grass, hair, oil, pine needles, pollen, and other debris that can clog your pool's filtration system. Suitable for pool skimming baskets with a diameter of 2-3/4~7 inches, these filter socks protect the pump impeller and shaft seal, extending the life of your pool filtration system. Cleaning your pool filter basket is a breeze with these skimmer socks. Simply wash with a garden hose and reuse or replace as needed. By reducing the frequency of cleanings, you'll have more time to enjoy water activities with family and friends. These socks are very stretchy and fit most pool pumps, filter baskets, and skimmer baskets. Just stretch them over the skimmer basket, put it back in place, and replace regularly for optimal performance.
