It’s not an easy task to differentiate between purification and filtration at a first glance. So, we often misunderstand the concept while making the water drinkable with multiple cleaning processes.

Purification is essential to remove unwanted particles from the contaminated water as the sourced water isn’t totally safe to drink. Though both processes have the same duties, there’s a technical difference between filtration and purification. And you’ll know the rest at the end, which one is better for purification.

Let’s face the battle and discuss the difference between filtration and purification. Though the basic duty is to purify water in both processes, there’s the difference that we’ve discussed here.

Difference Between Filtration and Purification

What is it?


Filtration is a process to remove dirt from the sourced water through physical, chemical, and other technical ways.

Purification is similar to water filtration where the process also adds some additional steps to kill the viruses. Like, mixing bleach powder and chlorine would be examples of purification without filtration.

All of these cases are able to kill microorganisms but can’t remove the physical contaminants. Precisely, boiling water can leave the impurities left behind as it makes the water evaporate.

So, water purification is a mandatory step, whether the source of water is. If the water is purified but not filtered, it might leave a sand grittiness. Besides, it doesn’t contain harmful bacteria and viruses that can affect you.
