Efficient debris capture: These pool filter socks trap dirt, leaves and other particulate matter before it reaches the main filter element, helping keep pool water clearer and reducing clogging. Fits most standard filter baskets: Designed to slide over and contain common pool filter baskets. The elasticized opening secures the sock in place without additional fasteners. Simple, tool-free installation: Just slip the sock over the filter basket — no tools or complicated steps required. Quick to install and remove for cleaning. Durable polyester construction: Made from polyester fabric that resists tearing and holds up to repeated use and exposure to pool chemicals without degrading quickly. Reusable and low maintenance: Rinse or shake out the sock between uses. Reusable design extends the life of your main filter cartridge and reduces the frequency and cost of replacements. Cost-effective protection: By capturing large debris and reducing strain on the filter element, these socks help lower maintenance costs and keep filtration performance consistent. Reliable filtration performance: The weave and material balance good flow with effective particulate capture so filtration efficiency is improved without excessively restricting water flow. Typical applications and scenarios: After heavy leaf fall: Install the sock during autumn or after storms to prevent leaves from filling the basket and reduce the need for frequent skimming. Post-party cleanup: Capture hair, sunscreen flakes and other small debris quickly after events, reducing load on the cartridge filter. Routine pool maintenance: Use as a preventative measure in everyday pool care to minimize cartridge cleaning and replacement frequency. What you get: A simple, durable filtration accessory that fits most standard pool filter baskets, installs in seconds, and helps protect and extend the life of your pool’s filter system.
