High-Purity Water for
Drinking and Cooking,
Finished With Balanced Alkalinity
A 5-Stage Alkaline Reverse Osmosis system by Puronics is a point-of-use drinking water purification system designed to produce exceptionally clean water at a dedicated faucet.
Water The Facts recommends reverse osmosis only when it makes sense for the water and for the household. Not every home needs RO, and we will tell you when it is not necessary.

What Reverse Osmosis Is
Reverse osmosis (RO) is a water purification method that uses a semi-permeable membrane to reduce dissolved substances in water.
RO is especially effective for improving drinking water purity because it targets contaminants that are dissolved and not always addressed by basic filtration.
A point-of-use RO system is installed at a single location (typically the kitchen sink) and is used for drinking and food preparation only.
What a 5-Stage RO System Is Designed to Reduce
A 5-stage reverse osmosis drinking water system is commonly used to reduce:
Dissolved solids (TDS)
Chlorine and chlorine byproducts that affect taste and odor
Heavy metals such as lead and arsenic (when present and depending on conditions)
Nitrates and other dissolved compounds
PFAS and other chemical contaminants (depending on conditions and system design)
Taste and odor-causing substances
Result: highly purified water intended specifically for drinking and cooking.

Why This System Includes an
Alkaline Remineralization Stage
Traditional reverse osmosis produces very pure water, but it also removes naturally occurring minerals that contribute to taste and mouthfeel.
The alkaline stage is added to:
Dissolved solids (TDS)
Chlorine and chlorine byproducts that affect taste and odor
Heavy metals such as lead and arsenic (when present and depending on conditions)
Nitrates and other dissolved compounds
PFAS and other chemical contaminants (depending on conditions and system design)
Taste and odor-causing substances
This creates water that is not only clean, but also pleasant to drink day after day.
What Reverse Osmosis Does Not Do
RO is extremely effective at purification, but it has a specific role. A point-of-use RO system:
Does not treat water for the entire home
Does not replace whole-home filtration, conditioning, or UV purification
Does not disinfect whole-home water supplies
This is why RO is typically used as a targeted solution at the sink, not as a whole-house approach.

TECHNICAL OVERVIEW
5-Stage Alkaline
RO System
For homeowners and professionals who
want a technical summary:
System Type
Point-of-use reverse osmosis drinking water system with alkaline remineralization
Installation Location
Under-sink or nearby cabinet location with a dedicated RO faucet
Primary Function
Reduction of dissolved contaminants for drinking and cooking water
Core Treatment Method
Semi-permeable RO membrane plus multi-stage filtration
Finish Stage
Alkaline remineralization to reintroduce minerals and balance pH
Use Case
Drinking water and food preparation only
(not whole-home)
Performance Factors
Incoming water chemistry, pressure, and
usage demand
When a 5-Stage Alkaline RO Is
a Smart Recommendation
Reverse osmosis may be recommended when:
Homeowners want the highest quality drinking water possible
Testing shows elevated dissolved solids (TDS) or other dissolved contaminants
Taste, odor, or confidence in drinking water is a concern
A dedicated drinking water solution is preferred over whole-home purification
Not every home needs RO. When it is not necessary,
we say so.

Common Questions About
Reverse Osmosis
Is reverse osmosis safe for daily drinking?
Yes. Reverse osmosis is widely used for drinking water purification and is considered one of the most effective methods for reducing dissolved contaminants.
Why not use RO for the whole house?
RO is designed for drinking water. Whole-home water is typically handled through conditioning, filtration, and disinfection when needed.
Does RO waste water?
RO systems use water during the purification process. Modern systems are designed to operate efficiently, and expected usage is explained during system selection.
Why add minerals back after purification?
The alkaline stage improves taste and mouthfeel and helps balance pH after the water has been highly purified.
