Superior Clarity
Glass Pearls have a small effective size of only 0.6mm to 0.8mm. Its 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.

Save Water
Glass Pearls spherical smooth shape, results in a low co
efficient of friction, reducing its backwash water requirements.
Glass Pearls backwashes with up to 20% less water than sand,
saving time and water.

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