Is There a Significant Difference between Filtered Water Providers?

Filtered water is one of the biggest selling products in the world today. Since filtered water is such a profitable commodity, it is not a surprise that there has been a significant boom in the industry of water filtration. In fact, there are countless filtered water providers with products on grocery store and corner market shelves. But the question is, is there any difference between these providers?

The primary difference lies in the water filtration system. There are so many different ways to filter water. Filtered water providers make use of different methods of purifying the water that they sell. Below, you will find some of the most common methods employed. Studying each method would make it easier for you to choose which one you think is most suitable for you and your family.


Perhaps the oldest form of water filtration, distillation, is done by heating water to a boiling point until it vaporizes. The vapor is condensed and stored in a separate container. The primary advantage of this method is to kill bacteria and organisms through extreme heat. Contaminants are left in the heated container. This method is effective except that there are some substances that cannot be removed even after heating water to a boiling point. Also, this method uses too much energy. Very few filtered water providers make use of this process.

Ion Exchange

In this process, there is an exchange of ions, which happens when water is made to pass through a spherical resin material. The ions of the water are replaced with the ions attached to the material. This process deionizes and softens the water. It works best when used with carbon filtration, as this method is not able to eliminate the bacteria that can be found in water.

Carbon Absorption

This method involves passing water through carbon filters to get rid of not only microorganisms and chemicals, but also unpleasant smells and tastes. This method of filtering water does not have any kind of effect on the hardness of water. This is also one of the most popular ways to filter water that is used both at home and in commercial water filtering stations. The two certified systems used for this method is the granulated carbon and the solid block carbon.


In this method, water is made to pass through an ultrafilter. This ultrafilter serves as a molecular sieve that removes dissolved molecules, microorganisms, colloids, and so on. This is an effective system that results in high-quality water. This process also uses less energy.

Reverse Osmosis

Reverse osmosis is said to be the most economical way of filtering water. The process can get rid of 99 percent of water impurities and contaminants. The process makes use of hydraulic pressure that is put on a concentrated solution to act against pressure from osmosis.
