What we use & why it matters

Inside the System

Every component NSF certified
7-Stage High-Precision Filtration
Dissolved solids

Down to 0.0001 Microns.

A human hair is about 70 microns wide. This system filters down to 0.0001 microns through a spiral-flow RO membrane, reducing dissolved solids, chlorine, organic chemicals and everyday contaminants. Seven stages of protection between the pipe and your glass.

Precision0.0001 micron
Alkaline Remineralization
Flat-tasting water

The Good Minerals, Back in.

Most RO systems strip everything out, including the minerals that make water taste great. The HW800 AlkaPro adds healthy minerals back in and balances the pH, so your water tastes crisp.

Tankless Design
Under-sink clutter

800 Gallons a Day, No Tank.

Maximum output and 70% less under-sink space. Water is treated the moment you ask for it, with a 2:1 drain ratio that sends far less water down the drain than a traditional tank system.

Twist. Swap. Done.

Filters twist out and twist in. No tools, no technician, no appointment. The auto-flush system even cleans the RO membrane by itself to make every filter last longer.

FAQ

Questions Homeowners Ask

Do you come to my home for a consultation?
Consultations are phone calls: you call or text us, we set a time and call you, go over your water and your home, recommend the right system at its published price and set your installation date. In-home presentations are available on request. Either way, the only required visit is the installation itself.
What does reverse osmosis do?
Reverse osmosis pushes water through a semipermeable membrane that rejects a broad range of dissolved solids, then delivers the treated water to a dedicated faucet at your kitchen sink. It is a point-of-use system for drinking and cooking water, not a whole-home system, which is why we pair it with whole-home treatment.
Tank RO or tankless RO — what's the difference?
A tank system slowly fills a pressurized storage tank so purified water is ready instantly. A tankless system treats water on demand, takes up far less under-sink space and has no storage tank. The tank system is $799 and the tankless HW800 AlkaPro is $999 on their own; either one is included free with any whole-home system.
Does the system treat every faucet?
Whole-home systems are installed where water enters the house, so every shower, faucet and appliance receives treated water. Reverse osmosis is the exception: it treats drinking water at one dedicated faucet.
