WaterLux RO Pro50
4-stage alkaline drinking water with a permeate pump. Up to 50 gallons a day.
What it does
WaterLux RO Pro50 sits under your kitchen sink and gives you a dedicated faucet for drinking and cooking water. Four stages work in order: carbon catches sediment and chlorine, a reverse osmosis membrane holds back dissolved solids, an alkaline stage adds calcium back and raises the pH, and a final carbon stage polishes the taste. A built-in permeate pump makes the system faster and more efficient, so you get more water at better pressure with less going down the drain. It makes up to 50 gallons of drinking water a day, and we can also hook it up to your fridge so your fridge water and ice come from the same filtered supply.
Best for homes with
- Bad taste in drinking water
- Buying bottled water
- Better coffee, tea and ice
- Filtered water and ice from your fridge
Good to know: WaterLux RO Pro50 filters drinking water at one faucet. For softer, filtered water through the whole house, pair it with WaterLux Complete.

How it works
Simple, automatic, out of sight.
Stage 1, carbon prefilter: catches sediment and the chlorine that affects taste and smell.
Stage 2, reverse osmosis membrane: holds back dissolved solids, including salts and hardness minerals.
Stage 3, alkaline remineralizer: adds calcium back and raises the pH for a crisp, clean taste.
Stage 4, carbon polish: a final pass for taste before the water reaches your faucet.
Maintenance
The filters are changed on a schedule and the membrane lasts for years. We will let you know the schedule for your system.
Questions
WaterLux RO Pro50 FAQ
Why is it called Pro50?
It makes up to 50 gallons of drinking water a day, more than enough for drinking, cooking, coffee and ice.
What does the alkaline stage do?
Reverse osmosis takes almost everything out of the water. The alkaline stage adds calcium back and raises the pH, which gives the water a crisp, clean taste.
What is a permeate pump?
A small pump built into the system that makes it work more efficiently. You get more water at better pressure, and less water goes down the drain.
Where does the system go?
Under your kitchen sink, with a small faucet added next to your regular one.
Can it connect to my fridge or ice maker?
Yes. We can hook up your fridge to WaterLux RO Pro50, so your fridge water and ice come from the same clean, crisp supply as your kitchen faucet.
