How a water softener works

Water softening utilizes a process called “ion exchange” to remove dissolved minerals such as calcium and magnesium.

These minerals can’t be trapped by a filter, so a molecular reaction is required. Water softeners have resin beads that hold onto sodium, and as hard water flows through the resin, the sodium is swapped for the hard water minerals. The hard water minerals are trapped inside the softener so they never reach your skin, hair or plumbing fixtures.

Frequently asked questions

What is hard water?

Hard water occurs naturally in more than 85% of the water supply in North America. Hard water contains dissolved minerals like calcium and magnesium. When this water dries, minerals stick to everything water touches — including your plumbing, hair and skin.

According to the Water Quality Association, hard water contains dissolved minerals above one grain per gallon (GPG), though relative levels of hardness have been established and are as follows:

Soft - less than 1 GPG
Slightly hard - 1 to 3.5 GPG
Moderately hard - 3.5 to 7 GPG
Hard - 7 to 10.5 GPG
Very Hard - 10.5 and higher GPG

What are the effects of hard water?

The presence of hard water in your home results in:

Limescale buildup around faucets or showerheads
Soap scum on shower walls, bathtubs, sinks and other fixtures
Plumbing and pipe corrosion
Streaky or spotted dishes
Stiff, scratchy laundry
Irritated, dry skin or dull, lifeless hair
Decreased efficiency of appliances and more frequent breakdowns
An increase in the amount of soap and detergent needed for cleaning

What is the difference between softening and filtering water?

You don't have to be a water expert to understand the basic principles behind water softening and water filtration. Here's an abridged version of what happens when you soften or filter water.

Softening water involves a process called "ion exchange" to remove dissolved minerals such as calcium and magnesium that can't be trapped in a filter bed. Softeners contain resin beads with sodium attached. As water enters the tank, dissolved calcium and magnesium are attracted to the resin. The resin swaps the sodium in exchange for the dissolved minerals, helping to remove the impurities from the water.

Meanwhile, filtering water involves the separation of particles from H2O. By passing water through a "filter bed" or "media bed", these granular particles are trapped and cleaner water flows to your tap. Water filters reduce a wider array of contaminants than water softeners.

Is it safe to drink softened water?

Yes, for nearly everyone it is safe to drink softened water. Some people are concerned that drinking softened water will increase the level of sodium in their diet. But the amount of sodium added to water during the softening process is low. If sodium levels remain a concern, combining your water softener with a reverse osmosis drinking water system can help to reduce salt and potentially harmful contaminants.
