iSpring RCC7AK, NSF Certified 75 GPD, 6-Stage Reverse Osmosis System, pH+ Alkaline Remineralization RO Water Filter System Under Sink, Superb Taste Drinking Water Filter
- 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 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. 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.
- 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.
