The Premier® Reverse Osmosis system is a filtration technology that blocks particles and chemicals in a series of stages, to provide the user the best quality drinking water possible. This easy to maintain system comes complete with a faucet and storage tank.
STAGE 1 • Sediment Filter – Reduces suspended particles such as dirt, dust and rust.
STAGE 2 • Carbon Filter – Reduces volatile organic chemicals, chlorine and other taste and odor causing compounds.
STAGE 3 • Membrane – Heart of the Reverse Osmosis system, rejecting up to 98% of total dissolved solids in the water.
STAGE 4 • Granular Activated Carbon Filter – Final stage of Reverse Osmosis, which polishes the water, making it ready to drink.
