As a home-owner I was looking for a solution to the problem of hard water. Hard water creates limescale on the dishes, pipes and appliances, causes extra dryness of the skin or extra fragile hairs. Doing my research I found that most common facilities for water treatment are water filters and water softeners.
Making the choice between a water softener vs. a water filter can be challenging without knowing how these two methods of water treatment are working. After I figured it out, I had no problem in making the right decision. So if you read further I will take you through the basics and principals of these two methods. I will show you how this applies to your water treatment needs.
Less developed parts of the world are places where filters can be critical to life, but most water in North America is potable from the tap through community efforts. Because of this, both softeners and filters that are purchased in the western world are typically chosen based upon
This means that you have the freedom to choose what is important to your family as you make consumer decisions about purchasing these appliances.
While a water softener may protect a home from the harmful buildup of minerals and keep appliances clean, but a water filter will eliminate other water problems such as bacterial contaminants, heavy iron problems, or chlorine. Whatever your water issues, the first point of making decisions about water softeners and water filters is having a general understanding of how they each work.
How Do Water Softeners Work?
Created specifically to eliminate or change the minerals that make water “hard”, softeners typically use an ion exchange process to trade magnesium, calcium, and manganese for another mineral—often salt.
Resins are covered in a solution of sodium (or sometimes potassium chloride) so that when the hard water comes into contact with it, the magnesium and calcium ions remain in the resin and are replaced by sodium ions. Here is what Environmental Protection Agency of United States has to say about sodium in drinking water.
For folks who prefer not to add salt or other chemicals to their water (although there is no proof of this being detrimental to the health), there are salt-free alternative systems. These often use a “magnetic” attraction to neutralize the minerals.
This type of process may be attractive to some people because it leaves the minerals in the water for health purposes, but eliminates their ability for the minerals to produce the scale and buildup that would typically be found in hard water.
In order to continue trapping the minerals, the resin must be periodically cleaned. This regeneration happens in a cycle that is determined by either a timer or on demand. A timed regeneration process typically happens every three days at night when the water is unlikely to be used because soft water is not available during the cycle.
The demand-initiated style of water softener will regenerate only when the capacity of the unit has been depleted. Some on-demand systems have two tanks which allows for the use of one while the other regenerates.

How Do Water Filters Work?
While naturally clean water may be found in certain places with fresh springs, most of the time water is taken from sources which need to be purified before it is consumable. Filtering water can take place in a variety of ways and has been happening for centuries as humans have found the need for cleaner water--and learned many ways to accommodate that need.
The desire for clean water may be based on health concerns,

Choosing Between a Softener or Filter
As mentioned above, there are certain problems that may require a softener and others a filter. Discerning which you need is a matter of knowing what your water issues are, and often you’ll find that you have a various water issues which may reveal the need for a combination water filtration and softener system.
