The Difference Between DI Water and Distilled Water

Dec 4, 2023

As you begin looking into various water treatment systems for your business, you will learn the names of different water treatment products that are available for lease or purchase, as well as the type of water they produce. For example, have you heard of deionized water or DI water? How about distilled water? You may be wondering what the difference is and we have the answers for you! Knowing the difference between these two water types is important because confusing the two can lead to some complications for your business or production. 

How do distilled water and DI water compare?

Simply defined, distilled water is water that is boiled into a vapor. That vapor is then condensed back into a liquid inside a different container. This process results in purified water since some impurities do not actually boil and are left behind in the first container. 

With deionized water, frequently referred to as DI water, a significant portion of the mineral ions are removed through an ion-exchange chemical process. 

It is also important to mention that:

It is safe to drink DI water and distilled water.

Deionized water is the purest form of water since almost all of its ions are removed.

With its ions intact, distilled water conducts electricity. In contrast, deionized water does not.
