Protective Filtration System: The pool skimmer basket attracts and captures insects, leaves, hair, scum, live debris, pine needles, and other debris, preventing them from clogging the filtration system and facilitating their quick removal. Durable Material: The filter socks are made of ultra-thin and durable elastic nylon, reusable and easy to clean. Wash and reuse them as needed. Their elasticity allows them to be stretched enough to cover the skimmer basket. Easy Installation: Thanks to their elastic fabric, the filter socks fit perfectly on various shapes of skimmer baskets. Installation takes just a few seconds. Easy to remove from the basket. We recommend replacing them with a new smooth filter sock every 4 weeks. Wide Application: The skimmer basket filter socks make cleaning the pool basket easier and reduce mess. They extend the life of the pool filter. Also suitable for in-ground and above-ground pools, such as spas, hot tubs, black marble bathrooms, etc. Package Content: You will receive 30 pieces of skimmer socks, which are long enough to prevent dirt from entering the pump filter.
