800g Reusable Pool Filter Balls (30–50mm), an alternative to pool filter sand, suitable for pool filtration.

🏊【Pool Filter Ball Materials】The filter balls are made of polyester, a lightweight, highly permeable, and non-toxic material with high absorption capacity and long life. They were developed as a replacement for filter sand in sand-based pool filters. 800g of filter balls are equivalent to 28kg of filter sand; the significantly lower weight makes filtration much easier. 🏊【Significant Filtration Efficiency】Filter balls for quick and easy pool cleaning. The filtration rate is 4 times faster than conventional filter media and the recovery capacity is higher. They can trap even the smallest suspended particles and filter out grease and impurities. 🏊【Durable and Energy-Saving】Pool filter balls are washable and reusable. Unlike sand, they don't clog the filter and require less frequent cleaning. The high-quality filter material extends the life of the filter and is the perfect replacement for filter sand, filter media, and other materials. (Tip: Place the filter balls in a laundry bag and wash them in the washing machine.) 🏊【Versatile Use】Filter balls are not only suitable for pool cleaning systems, but also for water filtration in aquariums, swimming pools, filter pumps, and even for emptying pools.
