Superior Clarity: Grade 1 Glass Pearls have a small, effective size of only 0.6mm to 0.8mm. Their narrow particle size range allows in-depth filtration and extends operating cycles between backwashing. Glass Pearls have been laboratory tested to be able to effectively filter down to below 3 microns.

Safe and Smooth: Glass Pearls are spherical and do not have any sharp edges. They are safe to handle and safe to service. If there is ever a failure of the filter’s laterals and glass beads flow into the swimming pool, they pose no risk of injury to swimmers.

High Purity: Waterco Glass Pearls are manufactured from 100% pure glass and are chemically inert. Waterco Glass Pearls have been independently laboratory tested for leeching
contaminants and found to be well within Australian Drinking Water Guidelines. 

Save Water: Glass Pearls' spherical smooth shape, results in a low coefficient of friction, reducing their backwash water requirements. Glass Pearls backwash with up to 20% less water than sand, saving time and water. 

Reduced Pressure Loss: Glass Pearls reduces pressure loss by up
to 30% compared to other filter media.
