Distilled Water vs Purified Water: What’s the Difference and Does it Matter?

Everyone knows that it’s important to drink clean water. Contaminated water can make you ill. It can make you nauseous or give you a permanent partner in crime, if you know what I mean. If you don’t know what I mean, then I’ll tell you. Unclean water can give you a parasite, or worse, parasites. But, it seems that water isn’t labeled as clean and unclean, anymore. There are many different types of clean water. Two such types are distilled water and purified water. They’re both “clean” waters. However, they’re labeled differently. Why is that? Today, we’re going to discuss distilled water vs purified water. What’s the difference between the two? Also, do those differences matter in the long run?

What is Distilled Water?

Let’s talk about what these waters are. Distilled water has, virtually, no bacteria inside of it. Also, it has a very low contaminate rate. It’s contaminate rate is approximately 1ppm (parts per million). It’s a clean water that is safe to drink. However, drinking too much can be risky. This is because there are organic minerals inside the distilled water that aren’t always removed in the distillation process. The distillation process is how we make distilled water. Although, distilled water is considered “clean”, it’s important to drink it in moderation. Or, you can add extra purification processes onto creating your distilled water.

What is Purified Water?

It sounds simple, doesn’t it? Purified water is clean, pure water. Well, like most other things, there are criteria that the water has to meet to be labeled as purified. For example, the water has to contain less than 10ppm of contaminated materials. Contrary to popular belief, purified water isn’t the same thing as filtered water. There are a few distinct differences between the two.

Distilled Water vs Purified Water

So, now that we know what classifies these types of water, what’s the difference? It seems like they’re the same thing. Well, you’d be wrong to assume that. There is one primary difference between distilled water and purified water. That difference is the process we use to “clean” these waters. Distilled water goes through a process called distillation. First, you boil water. Then, you capture the steam from the boiled water. The steam is considered to be pure water. Lastly, you condense the steam back into water. This helps to eliminate bacteria and unwanted materials within the water. However, purified water goes through a variety of processes to be “cleaned”. Those other processes are reverse osmosis, ozonation, ion exchange, and sand filtration. There are other ways to purify water. However, these are the most common. The last difference is that distilled water costs more than purified water.


In conclusion, there are a few differences between distilled water and purified water. There isn’t a debate between distilled water vs purified water. However, many people may be unaware of the differences between the two. Both are safe to drink. However, don’t drink too much distilled water because that could become dangerous. Either way, you’re clear to drink both distilled water and purified water. One isn’t better than the other!
