The strong structure uses elastics and nylon mesh fabric to catch most fine particles such as silts, sand, greases, gypsum, and other debris. Pool socks protect pump impellers and shaft seals from damage and clogging, thereby extending the service life of pool filter systems. These nylon pool basket filter socks are made of mesh fabric with an enduring elastic band and are reusable many times. The easystretch fabric fits into your pool filter basket. The basket can be easily cleaned by washing, and filter socks should be discarded and replaced regularly. Use scenario: After storms or windy days, insert the sock to trap fine particles like silts and sand before they reach the pump, reducing clog risk. Use scenario: During routine pool maintenance, socks regularly to maintain filter efficiency and protect pump components. Use scenario: In pools with frequent fine debris, use the socks to help extend the life of the pump and filter system by catching debris at the basket level.
