  • Superior purity

    Whereas other filter media may contain a variety of contaminants, Waterco’s Glass Pearls are chemically inert for superior purity. In fact, Glass Pearls have been independently lab tested for leaching contaminants and found to be well within Australian Drinking Water Guidelines. Their superior purity greatly reduces its initial backwashing requirements, prior to commissioning a filter, enabling a rapid start up of media filters.




  • Safe

    Glass Pearls are safe to handle & safe to service in comparison to other glass media options as crushed glass. Glass Pearls are spherical and do not have sharp edges, making them really safe to use. And if there’s ever a failure, of the filter’s laterals and Glass Pearls flow into the swimming pool, they pose no risk of injury to swimmers.


  • Superior depth filtration

    Glass Pearls operate on the basis of “depth filtration”; dirt is driven through the filter bed and trapped in minute spaces between the particles of filter media allowing the cleansed water to pass through.

  • Glass Pearls are man-made to specific geometrical shapes providing an extremely narrow particle size range of 0.6mm to 0.8mm, enabling the creation of a dense homogeneous filter media bed, capable of filtering particles down to 3 microns. A micron is equivalent to one millionth of a metre.


Its spherical shape results in low coefficient of friction, reducing backwash requirements, saving time, water and money.
