Filter ball is the best filter material for swimming pool filtration and the perfect substitute for traditional filter sand. The filter ball is made of 100% polyester fiber and made of fiber. The filament not only ensures light weight, but also ensures excellent particle filtration. And unlike in filtering sand, it doesn't harden five times as much as in filtering sand.

 Compared with the traditional steel filter material, it has the advantages of lighter, more efficient, good elasticity, no floating on the water, large gap, long working cycle and so on.

 Why do more and more people choose to use fiber filter balls? The reason is that the filter ball is more clean. If the sand filter is used, there will be residual sand at the bottom of the swimming pool. If the filter ball is used for swimming pool water treatment, this situation will not occur, and the swimming environment will be more healthy.
