Reverse osmosis pushes water through a membrane fine enough to hold back dissolved solids, so what comes out is the cleanest drinking water most homes will ever have. Galene installs RO at the kitchen sink for drinking and cooking, or for the whole home where the water calls for it.
Two ways to use RO
Under-sink
A six-stage system with quick-connect filters, installed under the kitchen sink with its own faucet. Drinking water, coffee, cooking and ice from one tap, without buying bottles. An optional alkaline remineralizer adds minerals back for taste.
Under-sink, tankless
The same NSF/ANSI 58 certified reverse osmosis with no storage tank: filtered water on demand, more space under the sink, sanitary quick-connect cartridges and a stand-alone installation with no cabinet drilling. Designed to reduce PFAS, lead, fluoride and other unwanted contaminants.
Whole-house
For homes whose water needs more than filtration and conditioning can deliver, such as high dissolved solids or difficult well water. The RO-4 treats the whole supply, with storage and repressurization so every tap runs normally.
How reverse osmosis works
Each stage prepares the water for the next, and the membrane does the real work.
Remove particles and chlorine that would damage the membrane.
Holds back dissolved solids while water molecules pass through.
A final carbon polish for taste, with an optional alkaline remineralizer.
Treated water is stored and served through a dedicated tap, or repressurized for the whole house on the RO-4.

Straight answers. Anything specific to your home gets answered at the consultation.
RO produces a reject stream along with treated water. Under-sink units send a modest amount to drain while filling the tank; whole-house systems are sized and set up at the consultation so the ratio suits your home.
RO removes most dissolved minerals along with contaminants. If you prefer the taste of mineralized water, the alkaline remineralizer cartridge adds them back after the membrane.
Yes, with the right pre-treatment. Iron, sulfur and hardness are handled first so the membrane lasts. Your water analysis tells us what pre-treatment the RO-4 needs.
Under-sink pre- and post-filters typically change on a schedule, with the membrane lasting longer. Kits for the RO-6Q and RO-6S are in our shop, and auto-delivery is available.
Request an in-home consultation and we'll recommend under-sink or whole-house RO for your water.
