Our pool skimmer socks can help to protect the pump impeller and shaft seal from being damaged or blocked, and extend the life of the pool system. And help keep your pool clean! The pool skimmer socks are made of thick, ultra-fine nylon fabric, and they can be washed out and reused as needed, very cost-effective. These elastic filters saver socks are easy to install on almost all types of pool pumps, filters baskets, pool baskets, or strainer baskets. Simply stretch them across your skimmer basket and then place them back. A simple but efficient way to protect your pool filters! The pool skimmer socks can catch oil, hair, bugs, grass, pollen, leaves, pine needles, and other fine particles before they can clog up your filters. We suggest that replace the filters basket socks every 4 to 8 weeks.
