【Package Included】You will receive a set of 30 swimming pool filter bags. If your socks are too dirty to slow down the water flow, they should be replaced or cleaned every 4-6 weeks. 【High-quality Material】The pool skimmer socks are made of high-quality nylon fabric with good elasticity to cover the skimmer basket. Easy to stretch and not easy to tear. 【Proper Size】Pool skimmer sock size: 23 x 12 cm / 9 x 4.7 inches (good flexibility, maximum size: 46 x 26 cm / 18.1 x 10.2 inches). The skimmer sock features a small grid that prevents debris from directly entering your pool's filtration system, acting as a protective barrier to prevent damage and prevent clogging. 【Reusable】The fine mesh socks make cleaning your pool basket easier and cleaner. In addition, when the socks are dirty, you can simply clean them with a garden hose, keeping your pool clean and saving money.
