Pool filter ball Replaces filter sand: The pool filter ball is designed to the filter sand in your filtration system. 200 g of pool filter balls correspond to 7 kg of pool filter sand, offering filtration strength, fast filtration speed, long service life, good recyclability, good elasticity, and less leakage. materials and action: Made from acrylic fibres, polypropylene, and polyester yarn. The filter ball surface provides oxygen enrichment and repeatedly contacts wastewater to capture small suspended matter that is difficult to precipitate and remove. This supports sediment precipitation and overall cleaning. Product parameters: Weight: 200 g Filling density: 7085 kg/m3 Specific surface: 3000 m2/m3 Ball diameter: 20 ± 2 mm Density: 1.38 g/cm Filtration rate: 2085 m/h Dirt collection: 610 kg/m Moisture absorption: 0.40.5 Not easy to clog: The filter ball is lighter and more efficient than conventional sand filters. Filaments float with the water, making the gaps between the fillers variable and reducing the tendency to clog. Light weight, strength, large specific surface, and effective treatment and adsorption of wastewater. Applications and use scenarios Residential pools: Ideal for replacing traditional sand filters in home pool systems to improve filtration efficiency and reduce backwashing frequency. Commercial and public pool facilities: Suitable for mid to large filtration setups where faster turnover and reliable clog resistance are advantageous. Spas, hot tubs, and water features: Effective in smaller, use environments where consistent filtration and reduced maintenance are valued.
