Not All Filtration Systems Are Created Equal
If you’re dealing with water quality concerns — whether it’s taste, safety, or scale buildup — choosing the right filtration system is critical. But should you filter just your drinking water, or treat every drop entering your property?
Enter the two main options:
-
Point-of-Use (POU) systems
-
Point-of-Entry (POE) systems
Let’s break down what they are, when to use each, and how to know which setup will give you the best performance and peace of mind.
What’s the Difference Between POU and POE?
Point-of-Use (POU) Systems
Treat water at a single outlet, such as:
-
A kitchen sink
-
Refrigerator water line
-
Showerhead
Point-of-Entry (POE) Systems
Filter all water as it enters the property. Also called:
-
Whole-house systems
-
Whole-building filtration
When to Choose a Point-of-Use System
Best for:
-
Targeted drinking or cooking water filtration
-
Chlorine, taste/odor, or lead concerns at the tap
-
Renters or owners looking for budget-friendly solutions
-
Quick installation with minimal plumbing changes
Popular POU technologies:
-
Reverse osmosis (RO)
-
Carbon block filters
-
Inline refrigerator filters
Limitations:
-
Doesn’t protect your entire plumbing system
-
May require multiple units (kitchen, shower, etc.)
When to Choose a Point-of-Entry System
Best for:
-
Properties with hard water, iron, or sediment issues
-
Households using well water or managing multiple bathrooms
-
Owners wanting to protect pipes, water heaters, and appliances
Benefits:
-
Delivers filtered water to every tap, shower, and appliance
-
Reduces scale buildup and extends equipment life
-
Helps reduce chlorine exposure during bathing and laundry
Limitations:
-
Higher upfront cost and requires professional installation
-
May not provide fine-level filtration needed for drinking water safety
What If You Need Both?
Many clients choose a hybrid setup:
-
POE system for general filtration and plumbing protection
-
POU system (e.g., RO) for drinking and cooking water
This gives you the best of both worlds — safe water at the tap, protection at the main.
Choosing the Right Fit: Questions to Ask
| Question | Go With | Why |
|---|---|---|
| Concerned about drinking water safety? | POU | Targets lead, chlorine, and bacteria at the tap |
| Battling scale or sediment across fixtures? | POE | Treats water for whole-property protection |
| Want to protect appliances and plumbing? | POE | Reduces mineral buildup and wear |
| Need a simple install with low cost? | POU | Easiest to implement per outlet |
| Treating well water or high nitrate levels? | Both | RO for safety + POE for sediment/minerals |
