Deionized (DI) water, also known as demineralized water, has tons of uses. But you may be unsure which brands produce bottled deionized water or where to buy it.
This article provides the top 12 brands selling deionized water in the USA. We’ll also explain what deionized water actually means, what it’s used for, and whether it’s similar to distilled water.
What Is Deionized (DI) Water?
Deionized/demineralized water is purified water with almost all minerals removed. This is achieved through filtration using resin beads that remove essential minerals like iron, calcium, magnesium, and potassium.
What Is Deionized Water Used For?
Deionized water has tons of uses. They include cleaning, industrial, and household appliances.
Below are some common uses for DI water:
- In a humidifier – Deionized water has no mineral build-up. This helps with functionality, prevents allergy issues and skin dryness.
- Aquariums – It’s best for the fish tank since no mineral/bacteria build-up.
- Cosmetics – Deionized water is used in cosmetic products such as shampoo.
- Cleaning detergents
- Laboratory experiments
- Car components and cleaning – no mineral build-ups and it protects your car’s engine.
- Cleansing diets or fasting (consult your doctor or healthcare professional before undertaking these activities).
You can lower costs by choosing deionized water brands with reusable bottles. E.g., FreshPure Waters. Although it is a less popular brand, it has a significant focus on minimizing plastic pollution.

Is Distilled Water The Same As Deionized Water?
Distilled water and deionized water are both highly purified water.
Deionized and distilled water uses are more or less the same. However, the difference comes in the preparation process.
- Distilled water is made through distillation, where water is heated to steam. The steam is re-condensed in a separate container leaving almost all impurities in the original container.
- Deionized water is obtained from deionization, where water is filtered using resin beads that remove all ions. I.e., all dissolved salts are removed.
Another difference is that distillation takes more time while deionization is quicker.
Does DI Water Mean Distilled Water?
DI water means deionized water, which is ultrapure water. Distilled water is passed through reverse osmosis and deionization membranes to make it deionized (DI) water.
Should I Use Deionized Or Distilled Water In My CPAP Machine?
Manufacturers and health practitioners recommend using distilled water in the CPAP machine’s humidifier chamber.
Distilled water helps the machine run smoothly and prevents bacteria from entering your lungs. It’s also ideal for optimum air pressure.
Additionally, distilled water is pure; hence no mineral build-up in your humidifier.
