Know before you buy
The system measures 18.2" x 6.25" x 16.72". Because it features a tankless design, it is significantly more compact than traditional RO systems, leaving you with more usable storage space under your cabinet.
No, the 3:1 ratio is actually highly efficient for a reverse osmosis system. For every four gallons of water processed, three gallons are purified for drinking and only one is sent to the drain, which is a significant improvement over older systems.
Reverse osmosis removes almost everything from your water, including beneficial minerals. The alkaline remineralization stage adds essential minerals back into the water, which balances the pH level and results in a crisper, more refreshing taste.
The system is designed for straightforward DIY installation. Most users can complete the setup in under an hour, provided they have basic tools and access to standard plumbing connections under the sink.
The smart faucet includes a real-time monitoring display that tracks your water quality and filter life. It will provide clear alerts when it is time to replace a filter, so you don't have to guess or keep a manual log.
Not at all. The 1600 GPD (gallons per day) capacity is fast enough to provide a high-pressure, continuous stream of water directly from the faucet, eliminating the need for a bulky storage tank.
