iSpring RCC7AK 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization – Natural pH WQA Gold Seal Certified (NSF/ANSI 58)
- High Capacity Reverse Osmosis water filtration for safer, healthier water. This under sink mounted water filter and water softener removes up to 99% of over 1,000 contaminants, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, hormones, asbestos, calcium, sodium, bacteria, giardia, viruses and more.

- Experience clean, safe, good-tasting water every time you turn on the faucet. Enjoy crystal clear ice cubes, fresher tea and coffee, better tasting foods, healthier baby formula – even better than most bottled water.

The iSpring RCC7AK includes an additional sixth stage – an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives the water a more natural taste than regular 5 stage RO water.
- Premium quality components ensure highest reliability and low maintenance for many years to come. Clear see-through 1st stage housing makes filter inspection a snap.
- Easy, do-it-yourself installation, typically in a couple of hours with industry-leading help just a phone call away. Fits under a standard kitchen sink, with all parts included and clear, well-organized instructions and videos.
