Four Stages For Better Drinking Water
Stage 1 & 2: A combination filter, with 20 micron mesh and granular activated carbon, remove dirt and rust while reducing chlorine and organic compounds.
Stage 3: The reverse osmosis membrane reduces dissolved salts, metals, microorganisms and other impurities.
Stage 4: A coconut-based granular activated carbon postfilter is the final step in giving you fresh tasting, clear water.

REPLACEMENT PARTS
When properly maintained, the Sierra system will provide you with years of trouble-free service. The cartridges in this system must be replaced on a regulas basis to maintain efficiency and to ensure high water quality. Test your water every 6 months using a Digital TDS meter. Consider membrane replacement when the TDS rejection falls below 85%.
