Stage1.
Tap water flows into the first Polypropylene filter which filters suspended solids to 5 microns.

Stage 2.
 41/2" X 10" Granulated Activated Carbon/KDF Prefilter begins the anti-scaling process and removes chlorine in the water supply.

Stage 3. 
3/4" diameter 5-10 GPM Anti-Scaling Device suspends calcium, causing scale not to stick to Reverse Osmosis Unit.

Stage 4. 
Reverse Osmosis Membrane separates water and removes 92% to 95% of total dissolved solids.

Stage 5
. The De-Ionization Cartridge removes the remaining total dissolved solids, producing water that is 99.9% pure.
