3.6 LBs Pool Filter Balls for Sand Filter, Reusable Pool Sand Filter Balls, Eco-Friendly Pool Filter Media Balls for Swimming Pool, Aquarium Tank (Equals 120 LBs Pool Filter Sand, White)

2026 Upgraded Filter Balls: The pool filter balls for sand filter effectively replace traditional filter sand, DE, and cartridges, offering a lighter, eco-friendly, and efficient upgrade for pool care. Approximately 3.6 lbs of filter balls provide filtration performance equivalent to 120 lbs of sand, making replacement quick and effortless without heavy sandbags, messy changeouts, or compacted filter media inside the tank
Finer Filtration, Clearer Water: Crafted from non-toxic, high-quality polyester fiber, these white swimming pool filter balls are safe for use around family and pets. The fluffy fiber structure provides strong adsorption and high impurity removal efficiency, while its 98.5% porosity supports smooth water flow with minimal resistance, helping reduce maintenance effort and deliver stable, long-lasting filtration performance
Micron-Level Filtration: The sand filter balls capture particles as small as 35 microns, effectively filtering fine micro solids and floating impurities such as cottonwood pollen, hair, leaves, and small debris. This helps reduce cloudy water and improve visible clarity, while the standard 2-inch diameter helps prevent clogging, reduce pressure buildup, and support stable system operation during daily pool filtration
