1. Made with elastic, ultra-fine nylon mesh, these pool filter socks function like nets, effectively capturing and trapping leaves, grass, hair, scum, oil, pine needles, pollen, insects, and other debris to help prevent clogging in the swimming pool filtration system. 2. Protects the swimming pool filter and pump components such as the impeller and shaft seal from damage by blocking debris, helping to extend system life. 3. Shallow mouth design allows for easy cleaning and convenient handling, reducing mess and improving maintenance efficiency. 4. Easy to install: the stretchable fabric fits snugly over the basket, ensuring a secure fit, and can be quickly installed or replaced. 5. When dirty, rinse with clean water for reuse; replace if heavily soiled. Replace every 4 to 8 weeks for optimal performance. Do not use with chlorine tablets, as they may degrade the material.
