Superior Water Purification
HOW IT WORKS
Sterling Water Coolers water purification products take unfiltered water and put it through a filtration and purification process unmatched by our competition. Unlike other systems, our products use five filters*:
Sediment Filter | Carbon Block Filter | 80 GPD Reverse Osmosis Membrane | Carbon Block Filter | Activated Oxygen Filter
*In certain cases, the reverse osmosis filter may be substituted with a microfiltration layer.
