While some locations offer water that’s safe for consumption, polluted water is a major problem worldwide. Depending on where you live, the water may be contaminated with various chemicals. This is when water purification comes into play.
There are a few different ways to purify water, distillation and basic purification being among them. Distillation refers to the process of boiling water and collecting steam, whereas purification is a broader term that describes how impurities, contaminants, and other particles are removed from the water.
The main differences between distilled and purified water are associated with the purification techniques used and the level of water purity achieved.
However, there are a few more distinctions that make purified and distilled water suitable for different applications. Keep reading to learn more!
What Is Distilled Water?
Distilled water is a type of purified water in which both contaminants and minerals have been removed. These include chemicals that can make your water taste bitter.
To understand the differences between distilled and purified water, let’s first take a closer look at the characteristics of distilled water.
How Is Distilled Water Made?
Distilled water is made through a process called distillation.
Regular water is heated to its boiling point, allowing the liquid to turn into vapor. As the vapor condenses, it turns back into water with no minerals or chemical impurities.
That being said, the distillation process separates the components of water through evaporation and condensation.
Methods to Make Distilled Water at Home
Buying distilled water over and over again can be pretty expensive. Luckily, you can make your own distilled water at home without using fancy equipment.
To make distilled water at home, follow these steps:
- Step 1: Get a large pot and fill it with ½ to ⅔ water.
- Step 2: Place a bowl inside the pot so that it floats or you can use a metal rack to keep the bowl in place.
- Step 3: Turn the heat on and let the water boil.
- Step 4: Place the lid upside down and fill it with ice cubes to create condensation.
- Step 5: Observe how hot steam hits the cold lid as this is the process through which you collect distilled water in the bowl.
- Step 6: Continue the distillation process until you have the needed amount of distilled water in the bowl.
- Step 7: Pour distilled water into a container of choice once it cools down.
When using this method to make distilled water, ensure that the water that is being collected in the bowl doesn’t boil. Simply adjust the heat if you notice that it begins to boil.

What Is Purified Water?
Water purification is the process of removing major impurities, such as chemicals and contaminants. Purified water is a broader concept and, unless specified, it doesn’t involve the removal of minerals.
Below is everything you need to know about purified water and the purification process itself.
How Is Purified Water Made?
Oftentimes, purified water is made by removing impurities and contaminants, such as bacteria, fungi, algae, parasites, chemical pollutants, and traces of metals (usually copper and lead).
Some common water purification techniques are:
- Filtration: Water passes through filters that remove dissolved particles, chemical pollutants, and organic contaminants.
- Sedimentation: Solid pollutants are removed from water using gravity.
- Disinfection: Chlorine or chloramine is added to water as a disinfectant to kill disease-causing germs.
- Coagulation and Flocculation: The addition of positively charged chemicals to neutralize and remove negatively charged particles.
- Reverse Osmosis: Pressure is used to force water molecules to go through a semipermeable membrane, which filters out the contaminants.
- Distillation: Water is boiled, allowing it to evaporate and condense, giving distilled water.
- Deionization: The removal of ions through the process called ion exchange.
- UV Radiation: UV light is used to get rid of living organisms that contaminate water.
Ways to Purify Water at Home
Purifying water at home is as easy as pie. Depending on what level of purity you’re aiming for, you can choose from a few techniques.
3 methods to purify water at home include boiling, filtration, and chlorination.
Boiling is the cheapest and safest way to purify water. It makes the water pure enough for it to be safe for consumption.

Choosing between Distilled and Purified Water
When it comes to choosing the right type of water for you, it’s not really about selecting the best. This is because distilled water is not better than purified water and vice versa.
In fact, distilled and purified water have their ups and downs you should consider to determine which one is suitable for you.
Besides, it also depends on what you’re going to use the water for.
Is it for drinking or ironing clothes with a steam iron?
Do you need water to fill up your aquarium or you’re more into watering your plants?
Are you looking for the right type of water to perform lab experiments and quantitative analysis that yield accurate results?
Whatever the case is, determine the level of purity you need before choosing between distilled and purified water.
If you need water free of contaminants and minerals, go for distilled water. If you need minerals but the water still has to be pure, then use purified water instead.
Summing up, purified water is a broad term that includes a few different types of water. Distilled water can also be considered purified water that has been obtained through distillation.
While distillation is the only process that gives us distilled water, purified water can be made through a few different purification techniques.
Apart from being made in different ways, you can distinguish distilled water from purified water by looking at its content. Generally speaking, distilled water lacks contaminants and minerals, whereas purified water still has some mineral content.
