Different Types of Water Softeners for the Home – Home & Home Automation

In many places around the world, tap water is not always safe to drink. Most of the time the water has a high concentration of limestone and can be a health problem. To avoid this state of affairs, the use of a water softener is very important for water purification and mineralization. In this article, we will give you a comparison of different types of water softeners.

The main types of water softeners

There are two types of water softeners on the market, namely water softener without salt and water softener with salt.

Salt-free water softener

His work differs from the salt softener and exists in three categories. The first is a salt-free water softener by filtration. It works without electricity and is installed on the plumbing system. It consists of an antibacterial filter and a fine mesh particulate filter.

The second category is salt-free CO² water softeners, which introduce carbon dioxide into the water to soften the limestone present in the water. This prevents scale deposits that can clog your pipes.

The third category refers to salt-free water softeners by polarization. The latter changes the polarity of minerals with the help of a weak electrical charge. This type of softener retains mineral salts and prevents stagnation in pipes.

salt water softener

It is the softener most commonly used in many homes. It works in three stages. The first step concerns the entry of water into the softener to contact the resin saturated with sodium ions. In the second step, the sodium ion replaces the limestone and magnesium present in the water with salt. These two steps lead to a decrease in the hydrothymetric titer of water.

Despite the differences in operation, these two water softeners have common features. This is about :

  • salt tank;
  • resin container;
  • control system to adjust the softener flow according to your water needs.

The price of these water softeners varies depending on the brands (there are comparisons of the best brands on the net, for example, here is the price of a water softener in Belgium).

Softener size to choose which suits your needs

Household water consumption depends on the members of the household. So, to find out the size of softener you need, you must determine your annual water consumption and the water quality (also called hydrometric title) of your residential area.


A hydrometric title can be obtained by checking the quality of the water (soft or hard) listed on your water bill by contacting City Hall. You can also go to the Ministry of Health website for information on your area’s hydrometric title. You can also do your own hydrometric test using test kits available at gardening and home improvement stores.

How to maintain a water softener?

Maintenance of the water softener should be carried out once or twice a year to ensure its softening capacity. This interview lasts an average of only one hour.

To begin service, you must replace the filters, which vary according to the instructions given in the instructions for different models. The amount of salt specified by the manufacturer must then be poured back into the brine tank to the level provided for this purpose. Be sure to purchase salt suitable for water softeners.

It will also be necessary to clean and disinfect each compartment of the softener and all of these accessories with specialized cleaners or bleach. Finally, adjust the water flow.

To maintain your health and the condition of your pipes, you must use a water softener. This improves hygiene by filtering tap water. It is true that there are different methods of softening water, but the best is the use of water softeners.
