Prevent clogging: The mesh of the skimmer sock is very fine, helping to prevent debris from entering the pool filtration system directly. It acts as a protective barrier, reducing strain on the filter system, minimizing clogs, and extending the life of your equipment. This helps save time on pool maintenance, reduces cleaning effort, and makes pool care more efficient.Pool cleaning: The ultra-fine pool skimmer sock effectively captures oil, hair, insects, flowers, leaves, pine needles, trash, small stones, small toys, and other small debris and dirt particles that could otherwise clog your pool's filtration system. It helps protect the filter, prevent blockages, and simplify pool cleaning.Wide compatibility: Made from durable nylon fabric with excellent elasticity, the pool skimmer sock stretches easily and fits securely in most pool skimmers, pool pumps, and filter baskets without loosening. Installation is quick and simple. Ideal for use in residential pools, outdoor pools, and spas.Reusable prefilter: The skimmer sock is washable and reusable. It can be cleaned by rinsing with water, hand washing, or machine washing. Note: Chlorine can degrade nylon fabric over time. Avoid using the skimmer sock while chlorine tablets are actively dissolving in the pool to prevent damage.
