The filter balls are made of polyethylene and serve as a replacement for the conventional quartz sand that is normally filled into the sand filter system.
The advantages of the filter balls are that they can be cleaned in the washing machine and that the sand filter cannot be damaged by them, as is the case with quartz sand.
Over time, quartz sand makes its way through the screens inside the pump and often damages them to the point of total failure. You can't do that with the filter balls.
700g replaces 25 kg of filter sand and is enough to fill a conventional sand filter system.
