iSpring RCC7AK 6-Stage Superb Taste High Capacity Under Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization - Natural pH, White iSpring
iSpring
iSpring RCC7AK 6-Stage Superb Taste High Capacity Under Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization - Natural pH, White
  • 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 RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below. 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. For leak-free installation, simply push tubing ½ inch deep into quick-fitting connectors and lock - no threading pipes needed.
  • About Prop 65: this product contains PVC which is commonly used in plumbing pipes and fittings. The chemical intermediate in the production of PVC requires a Prop 65 warning. The system is BPA free and nothing will leach into the water.
