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.

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.

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. With any whole-home system, the tank RO is included free and the tankless is a $200 upgrade.
Can the reverse osmosis system feed my fridge or be installed in the basement?
Yes, with the tank reverse osmosis system. Every tank RO includes the standard installation: the unit under the kitchen sink feeding its own kitchen faucet. Each extra run beyond that is an additional fixture. One additional fixture is $500, for example a line to the refrigerator from under the sink, or a basement installation that feeds the kitchen faucet. Two additional fixtures are $750, for example a basement installation that feeds both the kitchen faucet and the refrigerator. The tankless unit delivers water on demand without a pressure tank, so it has to be installed under the kitchen sink.
