Waterco’s Microfine filter Media offers much finer filtration than other alternatives and are therefore capable of providing outstanding water purity and clarity (filtration below 3 microns). They also require 20 per cent less water for backwashing compared to sand.


Ultimate water purity

“Whereas other filter media may contain different contaminants, Waterco’s Microfine filter media is chemically inert for the ultimate water purity,”
“In fact, Waterco’s Microfine has been independently lab tested for leaching contaminants and found to be well within Australian Drinking Water Guidelines.”
At only 0.6mm by 0.8mm in size, the narrow particle size of the Glass Pearls enables in-depth superior filtration. The spherical shape also results in low friction levels, also reducing the need to backwash and saving pool owners both time and precious water.

Ultimate safety

Not only that, Microfine Glass Pearls are safe to handle and safe to service, “Unlike 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.”

Glass Pearls are also easy to install, enabling a rapid startup of the media filter. Plus its high purity means very little backwashing is required to cleanse the filter media prior to commissioning the filter
