Water Softening vs. Water Filtration

They're common questions we hear:

  • What's the difference between a water softener and a water filter? 
  • Which one is better for my home?

Maybe you've had the same questions. Let's start by looking closely at what each of these solutions does, and how they can help out around the house.

Water Softeners

As you might guess from the name, water softeners generally only refer to products that remove hardness-causing minerals and contaminants from water, like magnesium and calcium. While this still covers a variety of products, it's generally fewer than those considered "water filters." Softeners also typically use salt as the primary chemical agent in modifying the properties of water, while filtration can encompass many more methods to alter water, like reverse osmosis.

Water Filtration

Filters generally refer to any methods or systems that remove contaminants from water, including:
  • Metals such as arsenic, iron, or copper 
  • Industrial and pharmaceutical byproducts like pesticides or hormones 
  • Sediment and other organic troublemakers

As such, the term "water filter" can refer almost equally to systems that filter water throughout your home, smaller products that filter at the point-of-use, reverse osmosis filtration systems, and others in between.

How Can I Tell Which One To Use?

Since each of these solutions focuses on different water-related issues, deciding on a softener or a filter should largely depend on what's in your water. For example, if limescale buildup is a constant headache for you, that's usually a sign that water is hard and a softener will alleviate some of those frustrations. If your water tastes or smells strange, a filter might be the more effective choice to remove culprit contaminants from your supply.

A good way to find out, if you don't already know or suspect what's in your water, is to have a Culligan Man test it for you. The results will help you and your Culligan Man evaluate the best solutions, whether it's softening, filtration, or a combination of both.
