FILTER-SAVING SOCKS: A simple yet effective way to protect your pool filters! The skimmer socks trap oil, hair, insects, grass, pollen, leaves, pine needles, and other fine particles before they clog your filters. EASY TO INSTALL: These elastic filter socks are easy to install on almost any type of pool pump, filter basket, pool basket, or strainer basket. Simply pull them over your skimmer basket and replace it. DURABLE & REUSABLE: Made of thick, ultra-fine nylon, the skimmer socks can be washed and reused as needed, making them very cost-effective. We recommend replacing the filter baskets every 4 to 8 weeks. IDEAL POOL ACCESSORIES: Enjoy a finer filtration system and a cleaner pool. The skimmer socks trap all the debris, so your pool water keeps circulating, your filters work more efficiently, and your filtration system lasts longer! Note: Due to the different monitor and light effects, the actual color of the item might be slightly different from the color showed on the pictures. Thanks!
