1. Filter ball is widely used for pool water filtration. It’s light and easy to manage. Filter ball could replace sand, 10 times as effective as sand filtration. 

2. Our filter ball raw material passed the reach test, which prove that our fiber ball is environmentally friendly and non-toxic. It needs to be used in a separate filter and couldn’t be used with other filter materials.

3. During the filtration process, the gap of the filter layer gradually becomes smaller along the direction of the water flow, which is more consistent with the ideal filter material released from the upper and lower pores, high efficiency, fast filtration speed (20-85m/h), large interception capacity, good filtration effect.
