Universal design: Suitable for most pool baskets. The stretching diameter is 2.75-8.66 inches and 13-22 centimeters, suitable for most built-in and floor swimming pool filters.<br> Protect your filters: Save money by protecting your filtration system. The filter screen can capture dirt, sediment and dog hair before they enter the filtration system. They make a significant contribution to the effective operation of the filter, preventing sediment from clogging your pool filtration system and reducing the maintenance cost of the filter system. It is also suitable for spas, jacuzzis and jet bathtubs.<br> High-quality materials: Our socks are made of high-quality elastic superfine nylon to enhance durability, with particular attention paid to durability and performance. Meanwhile, by checking the densities of different base materials, it is ensured that the inflow and outflow of the swimming pool are always good without affecting the filtration effect.<br> Easy to clean: After using the filter socks, cleaning the pool basket becomes easier. If it gets dirty, rinse it with water for 10 seconds and then use it again. Or simply throw it away (if the pollution is serious). If there is no serious pollution, new swimming pool socks can be replaced after 4 to 8 weeks.<br> Keep your swimming pool clean: Using pool filter socks can absorb dirt and sediment, keeping your water shining. Save time playing in the water with your family/friends instead of using the boring, clean pool skimmer filtration system.<br> Name: Swimming Pool Filter Socks<br> Material: High-elasticity ultra-fine nylon mesh<br> Size: 13*22cm/5.12*8.66 inches (single tiled size)<br> Single gram weight: 5.5G<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
