Solid Mesh Skimmer Filter Protectors: Our pool filter socks are made of durable microfiber polyester fabric, featuring high quality, high elasticity, breathability, moisture-wicking, and strong acid and alkali resistance. They are easy to use and stretch, and can be reused multiple times. They help trap dog hair, dirt, grease, leaves, pine needles, tiny insects, and other debris, keeping your pool clean and comfortable. Protect Your Pool Filtration System: By using pool skimmer filter socks, you protect the pump impeller and shaft seals from damage or clogging, extending the lifespan of your filtration system and saving you money. The skimmer filter sock acts as a barrier, blocking pool filters and preventing debris from clogging them, ensuring efficient skimmer filter operation.

This simple, stretchy skimmer sock fits your pool filter basket perfectly; simply slide it over the edge of the basket or filter. It's incredibly easy to use. For best results, rinse or replace with water every 4-8 weeks. Versatile: Our pool skimmer socks come in packs of 30 for easy replacement. The sock fits all sizes and shapes of pool filter baskets, including spa pools, hot tubs, and jacuzzis. Warning: Do not use dissolved chlorine tablets in the pool skimmer basket, as this may corrode the sock.
