Filter balls for sand filtration systems: Filter balls are lighter than conventional filter sand, easier to fill and can be reused after cleaning. With their unique design, these filter balls provide superior filtration compared to traditional filter sand. Each 1.5lbs ball is equivalent to 50lbs of filter sand, ensuring cleaner and clearer pool water.
Significant filtration effect: The pool filter balls are made of 100% polyester fiber. It is an ultra-light, environmentally friendly material with a fine fibre structure, which can effectively filter tiny particles and impurities to achieve high quality filtration effects and ensure the quality of clean water.
Easy to clean and maintain: Please do not expose the pool filter balls to direct sunlight when in use. Supplied with a mesh bag and machine washable, the filter effect can be restored by cleaning with a small amount of washing liquid at 30° water temperature.
