When homeowners look to improve water quality, one question comes up often: Do I need a water filtration system or a water softener?

While both improve your water, they solve very different problems. Understanding the difference can help you avoid unnecessary costs and get the results you’re looking for.

Choosing the Right Water Treatment System

Water issues can show up in many ways — bad taste, odor, scale buildup, or dry skin. The right solution depends on what’s actually in your water.

Knowing whether filtration or softening addresses your problem is the first step.

What Is a Water Softener?

A water softener removes hard minerals like calcium and magnesium, which cause:

• Scale buildup in pipes
• Reduced appliance lifespan
• Dry skin and hair
• Stiff laundry

Softening improves comfort and protects plumbing but does not remove contaminants.

What Is a Water Filtration System?

A water filtration system removes or reduces:

• Chlorine
• Sediment
• Chemicals
• Unpleasant taste and odors

Filtration improves water quality and taste but does not soften water.

Pros and Cons

Water Softener Pros

• Protects plumbing and appliances
• Improves comfort and cleaning
• Whole-house coverage

Water Softener Cons

• Does not improve taste
• Requires salt and maintenance

Filtration System Pros

• Better tasting water
• Removes common contaminants
• Whole-house or point-of-use options

Filtration System Cons

• Does not address hard water
• May require filter replacements

Which Option Is Best for You?

Choose a water softener if:

• You have scale buildup or hard water
• Appliances are wearing out quickly

Choose water filtration if:

• Your water tastes or smells bad
• You’re concerned about chemicals or sediment

In many homes, a combined system (such as a HALO whole-house system) provides the best results.
