Please note: There are wet & dry membranes in the market and the ones we sell are the dry version. Comparing to the wet version, the dry ones can be stored longer, are easier to preserve (no need of vacuum sealing), and don't contain preservation solution that needs to be washed off before usage. The membrane normally lasts about 2-3 years depending on your source water quality. If your water is very hard (Total Dissolved Solids level above 750 ppm), please contact us for customized solutions.
iSpring RCC7AK, NSF Certified 75 GPD, Alkaline 6-Stage Reverse Osmosis System, pH Remineralization RO Water Filter System Under Sink, Superb Taste Drinking Water Filter (RCC7AK)
Certified to NSF/ANSI 58, 6-Stage Alkaline Remineralization Layered Filtration - Exclusively designed to restore the natural alkalinity and mineral balance of water; this reliable and ultra-safe Reverse Osmosis (RO) water filtration system converts your water into clean, pure and healthy drinking water by removing up to 99% of over 1,000 harmful contaminants like PFAS (includes PFOA and PFOS), chlorine, fluoride, lead (removes up to 98%), arsenic, asbestos, calcium, sodium and more.
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 DIY installation and all necessary parts for installation are included. Backed by clear installation manual, instructional videos, and access to lifetime technical support. The entire alkaline system fits nicely under a kitchen sink.
