【Perfect to protect the filtration system】： Our pool skimmer filter can protect the pump impeller and shaft seal from damage or clogging and extend the life of the pool filtration system. You don't have to worry about your filtration system being destroyed by these impurities. 【Wide compatibility】： The skimmer filter sock is suitable for almost all types of pool filters, baskets or skimmers (including pool skimmer socks for Hayward, Pentair, Swimquip, etc.) Installs in seconds, just slide the sock over the basket and it's ready to capture debris from the water. 【Super Value Pack】： 30 pool skimmer socks. 12 x 21.5 cm (LW).

Please do not use the product while you are dissolving a chlorine tablet in your basket. Otherwise, the pool skimmer sock will be eroded. 【Free Your Hands from Manual Cleaning】： With our pool skimmer socks,
