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.

LOW MAINTENANCE - Transparent 1st stage housing for easy visual inspection. Three extra long life pre-filters to remove large contaminants and protect RO membrane. 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.

EASY TO INSTALL & NO LEAKS - The water purifier is designed for do-it-yourself installation and all necessary parts for installation are included. Backed by clear installation manual, instructional videos, and access to life-time technical support. The entire alkaline water filter fits nicely under a kitchen sink.
