  • When it comes to clean water, water filtration and water purification seem to be interchangeable. If you buy a water filter for your drinking water, you might say that you’ve purified your home’s drinking water. However, this isn’t true. There’s technically a difference between water filtration and purification.

    What is Water Filtration?

    Things home-owners should know about water softeners
    Water filtration is the process of using a porous substance to remove dirt, chemicals, and toxins from water. In many cases, activated carbon is used as a filter that must be replaced at regular intervals. Water filters are not effective enough to remove most of the toxins and contaminants that exist within municipal drinking water. These water filters often improve how the water tastes and smells, even if particles are left behind.

    What is Water Purification?

    Water purification goes beyond what a water filter is capable of. Using reverse osmosis, distillation, or deionization to sanitize the water, these systems can remove more than 90% of the contaminants in drinking water. Although each of these processes achieves similar results, the processes work in different ways.

    • Reverse Osmosis — water is forced through a porous membrane when subjected to strong osmotic pressure to remove ions and particles
    • Distillation — separating water with evaporation and condensation, such as through boiling
    • Deionization — removes ions with negatively charged particles

    What’s the Difference?

    Water purification removes more toxins and pollutants from the water than water filtration can. Purification can remove smaller pollutants because it relies on a more comprehensive process than simply having water pass on its own through a porous surface. As a result, many water purification systems may be more expensive and less common than water filtration systems. Most of the inexpensive drinking water pitchers available at grocery and big box stores are water filters.

    What are the Advantages of Water Filtration?

    Water filtration can still be a valuable process in many applications. Here are some advantages of water filtration systems:

    • Often less expensive than water purification systems
    • Remove many of the most dangerous contaminants that should be avoided, including mercury and lead
    • Easy to replace activated carbon cartridges
    • Systems can easily be purchased as pitchers and sink attachments in local stores

    What are the Advantages of Water Purification?

    There are many reasons why a water purification system might be a better choice for your family. These include:

    • More effective than water filtration systems
    • Removes up to 90% of contaminants from drinking water
    • Many of these systems need to be installed by a trained professional
    • Some systems need cartridges replaced less often

    When Should You Use Water Purification?

    Since water purification removes more pollutants from water, it would be easy to conclude that you should opt for water purification over a filtration system. This may or may not be the case. Water purification makes for the cleanest drinking water, so it’s a great solution for people who want to purify their home’s drinking water that comes from municipal taps. However, water purification is also beneficial to businesses who need access to pure water, too.
