About This
- HIGH-QUALITY US MADE FILTERS - The PH100 RO Water Filter System features top-quality US-made filters and a Dupont RO membrane for exceptional durability and performance. This advanced under-sink reverse osmosis system removes up to 99% of over 1,000 contaminants, including PFAS, lead (up to 98% removal), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.For the ice maker water line, please search "B09MV3SNT3".
- FAST FLOW & LESS WASTE WATER - 100 GPD, the alkaline Reverse Osmosis system is up to 1:1 pure to waste water ratio. Enjoy crystal clear ice cubes, coffee, baby formula – even better than most bottled water. With upgraded 3/8” fast flow input and output design, the Reverse Osmosis water filter increases flow rate that produces clean, fresh, safe water. The entire alkaline 6 stage RO system fits under a standard kitchen sink.
- GREAT TASTING ALKALINE WATER - The RO membrane of the under sink Reverse Osmosis water filter system removes not only harmful pollutants but also a few helpful minerals. A standard 5 stage under sink RO system produces slightly acidic water with a pH of 7. 0 or below. This Reverse Osmosis water filter includes an additional 6 stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, making water taste better.
- EASY TO INSTALL & CHANGE FILTERS - Easy, Do-It-Yourself installation, typically in a couple of hours with knowledgeable technical support just a phone call away. Extra tool sets are included in the RO water filter system. Comes with clear manual and installation videos. For leak-free installation, simply push tubing ½ inch deep into quick-fitting connectors and lock, no threading pipes needed. Clear see-through 1st stage housing makes filter inspection a snap.
- 100% CUSTOMER SATISFACTION - Backed by a 1-year Manufacturer with lifetime support from Atlanta, GA USA. Features a beautiful European-designed brushed nickel all-metal faucet. For the US Made replacement reverse osmosis filters, please search “F9KUS” or “F19K100US”. This alkaline water filter system is to deliver endless bottled quality drinking water right in your home for many years to come, eliminating plastic bottles.
