The ion exchange is a process of filtering water through bead-like spherical resin materials that are called ion-exchange resins and the filter used in this process is called ion exchange water filter.

Ions in the water are exchanged with other ions that the beads contain.

The two most common ion-exchange methods are softening and deionization. 

In simple words, when magnesium and calcium ions found in hard water, these two ions of hard water are contaminated and then there is a process involved for an exchange of these ions with less contaminated sodium or hydrogen ions.

The magnesium and calcium ions have a positive charge and the sodium ions carry a negative charge and because of these opposite charges they attract each other and in this way ions are exchanged.

Ion Exchange filters are very efficient in removing dissolved inorganics and it is a regenerable process.

It is relatively less expensive and just requires an initial capital investment.

Final Thoughts

Water softening and purification is very important in daily lives to keep ourselves healthy.

Ion exchange water filters are a very reliable method to soften and purify water by softening its hardness.

They must be adapted and used because they remove hard ions like magnesium and calcium ions from water and exchange them with necessary ions like sodium ions.

It is a very effective and efficient water softener with no perforation of substances into the soft water. Most of the heavy metals derived from water can be reused.

The wastewater that is produced by ion exchange machines is also used for various water treatments.

However, one major must be considered that is because the sodium ion that creates a high level of acidity in the water when it is consumed for drinking. It can also harm some crops and plants where the water is used for watering.

However, there are several ion exchange water filters available online and you can choose depending on what you want.

Whether you want a whole system for water filtration and water softener for your entire house or you want just a pitcher of clean and soft water to drink, there is plenty of water treatment options available in the market for your convenience.

These are just 10 best options out there right now.
