If you're shopping for better water in Ada, Oklahoma, you've probably come across two common solutions: water softeners and water filters. While they may sound similar, they solve very different problems. Understanding the difference is the first step toward choosing the right system for your home.
At Diamond Plumbing, one of the most common questions we hear is:
"Do I need a water softener, a water filter, or both?"
The answer depends on what's in your water—and what problems you're trying to solve.
The Short Answer
Think of it this way:
A water softener removes hardness minerals like calcium and magnesium.
A water filter removes contaminants that affect taste, odor, appearance, or overall water quality.
Many homeowners in Ada benefit from both forms of water treatment.
What Is Hard Water?
Hard water contains elevated levels of dissolved minerals, primarily calcium and magnesium. These minerals naturally dissolve into groundwater as it moves through rock and soil and are common throughout much of Oklahoma.
While hard water isn't generally considered unsafe to drink, it can create numerous problems throughout your home.
Common Signs of Hard Water
If you live in Ada or the surrounding area, you may notice:
White spots on dishes and glassware
Soap that doesn't lather well
Dry or itchy skin after showering
Hair that feels dull or difficult to manage
Mineral buildup on faucets and showerheads
Scale inside plumbing pipes
Reduced water heater efficiency
Higher energy bills
Appliances that wear out sooner than expected
These are all classic symptoms of hard water.
What Does a Water Softener Do?
A water softener does not filter your water.
Instead, it removes calcium and magnesium through a process called ion exchange. The system replaces hardness minerals with sodium or potassium ions, preventing scale from forming inside your plumbing system.
Benefits of a Water Softener
A quality water softener can:
Protect your plumbing from scale buildup
Extend the life of your water heater
Help appliances last longer
Reduce soap and detergent use
Leave dishes cleaner and spot-free
Make towels and clothing feel softer
Improve shampoo and soap performance
Help skin and hair feel healthier
Lower long-term maintenance costs
For many homeowners, preventing expensive plumbing and appliance repairs is one of the biggest advantages of soft water.
What Does a Water Filter Do?
A water filter is designed to remove unwanted substances from your water.
Depending on the type of filtration system, it may reduce:
Chlorine
Sediment
Rust
Sand
Sulfur odors
Organic compounds
Lead
Certain chemicals
Other contaminants depending on the filtration media
Unlike a water softener, a filter does not remove hardness minerals.
If your faucets have white scale or your dishwasher leaves cloudy spots, installing only a filter won't solve those issues.
Types of Water Filtration Systems
Different filtration systems serve different purposes.
Whole-House Water Filters
Installed where water enters your home, these systems improve water quality throughout the house by reducing chlorine, sediment, taste, and odors.
Every faucet benefits.
Reverse Osmosis (RO)
Reverse osmosis systems are typically installed beneath the kitchen sink and produce exceptionally clean drinking water.
They're ideal for:
Drinking water
Cooking
Coffee
Ice makers
Specialty Water Filters
Some homes require treatment for specific water conditions such as:
Iron
Sulfur ("rotten egg" smell)
Manganese
Tannins
Nitrates
The right solution depends on your home's water quality.
Water Softener vs. Water Filter Comparison
Water Softener | Water Filter |
Removes calcium and magnesium | Removes contaminants |
Prevents scale buildup | Improves taste and odor |
Protects plumbing | Reduces chlorine |
Extends appliance life | Removes sediment |
Makes soap work better | Improves drinking water |
Does not filter contaminants | Does not soften hard water |
Neither system replaces the other—they solve different problems.
Do I Need Both?
In many Oklahoma homes, yes.
A traditional whole-home water treatment system often includes:
A water softener
A whole-house carbon filter
Reverse osmosis for drinking water
This combination provides:
Softer water
Cleaner plumbing
Better tasting drinking water
Longer-lasting appliances
Lower maintenance costs
But today's technology offers another option.
One System That Does Both: Water-Right Impression Plus® RC Series
One question we hear from homeowners in Ada is:
"Do I really need both a water softener and a whole-house carbon filter?"
In many cases, the answer is no.
At Diamond Plumbing, one of our favorite solutions for homes on municipal water is the Water-Right Impression Plus® RC Series.
Unlike traditional systems that require separate tanks, the Impression Plus RC combines activated carbon filtration and water softening into one compact system.
What Makes It Different?
Inside a single tank are two specialized treatment media working together.
Activated carbon helps reduce:
Chlorine
Unpleasant tastes
Common odors associated with city water
At the same time, the softening resin removes:
Calcium
Magnesium
Hard water minerals that cause scale buildup
The result is water that is:
Softer on your skin and hair
Better tasting
Free from chlorine odors
Easier on plumbing fixtures
Better for water heaters and household appliances
Why We Recommend It for Ada Homes
Most homes in Ada receive municipally treated water.
That means homeowners are often trying to solve two common problems:
Hard water
Chlorine taste and odor
Rather than installing both a separate carbon filter and a separate water softener, the Water-Right Impression Plus RC solves both with one efficient, space-saving unit.
It also features smart regeneration technology that automatically adjusts based on your household's water usage, helping improve efficiency while reducing salt and water consumption.
For many Ada homeowners, it's one of the simplest and most effective whole-home water treatment solutions available.
Water Quality in Ada, Oklahoma
Water quality can vary from one neighborhood—and one well—to another.
Some homeowners primarily struggle with:
Hard water
Scale buildup
Dry skin
Mineral spotting
Others are more concerned about:
Chlorine taste
Sediment
Water odor
Drinking water quality
That's why we always recommend starting with an evaluation of your home's water rather than guessing which system you need.

Why Professional Water Testing Matters
The biggest mistake homeowners make is purchasing equipment before understanding what's actually in their water.
Professional water testing can identify:
Water hardness
Chlorine levels
Iron
pH
Sediment
Other water quality concerns
Once you know what's in your water, choosing the right treatment system becomes much easier—and you avoid paying for equipment you don't actually need.

Frequently Asked Questions
What's the difference between a water softener and a water filter?
A water softener removes hardness minerals like calcium and magnesium, while a water filter removes contaminants such as chlorine, sediment, and substances that affect taste and odor.
Can one system both soften and filter my water?
Yes. Combination systems like the Water-Right Impression Plus® RC Series use activated carbon to reduce chlorine, taste, and odor while simultaneously softening hard water. For many homes in Ada, this provides an efficient all-in-one solution.
Is hard water dangerous?
Hard water is generally safe to drink, but it can reduce appliance efficiency, shorten the lifespan of plumbing fixtures, and create ongoing cleaning and maintenance issues.
Should I install reverse osmosis if I already have a water softener?
Many homeowners do. A water softener protects your plumbing and appliances, while reverse osmosis provides exceptionally clean drinking water at the kitchen sink.
