【GREAT-TASTING MINERAL WATER】：A standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below because the RO membrane removes not only harmful pollutants but also a few helpful minerals. The iSpring RCC7AK Reverse Osmosis water filter includes an additional 6th stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives your water a more natural taste than regular 5 stage RO water filter.

Ultra fine (RO) filter to remove contaminants down to 0. 0001 microns; fine GAC filter to provide final polishing to the purified water and (AK) filter to finally restore just the right proportion of healthy minerals and a natural alkaline balance. The end result is great-tasting bottled-water quality.
