Today, many types of water purifiers exist, and they are designed to remove contaminants and other harmful elements present in the water. Dirty water, hard water, chemical-filled water, etc., are a problem all around the globe. Choosing a purification system is also problematic.
Drinking water can be a complicated task, be it from treated to filtered water to bottled or even pitcher filtered water. Taking the right choice is indeed more complicated. If by chance, a wrong purification system has been installed on your premises, it could be a long, hectic, and painful workload.
The main thing would be, the quality of water you are getting is unproductive and unhealthy. Changing the system would require additional cost and time. This is why we are here to guide you with the most appropriate purification system.
If you are on a hunt for pure water, you may have heard many methods, which is very confusing. Just in time, we are here to help you out. We will try to make you understand the difference between deionized and distilled water.
Both the water types are pure water, but both have a distinctly different process to purify the water. We will help you decide which system is healthy for you and fits the best for your premises.

WHAT IS DEIONIZED WATER?
Deionization of water is the way to purify water using the ion-exchange method. Put more simply, it means that those ions are removed to make the water pure.
The process involves where cations and anions are removed and replaced with hydrogen ions and hydroxide ions. Hydrogen ions(H+) and hydroxide ions(OH) react to form water.
Deionizing is done using an ion exchanger. This is a scientific method of purifying water. Deionized water removes ions and other dissolved solids; that is why it is considered one of the purest forms of water.
It is so pure due to no substance present in it. Its water taste and smell are also very different from that of normal water. However, deionizing removes all ions but does not filter water.
WHAT IS DISTILLED WATER?
Distilled water is also one of the purest forms of water. And it is the oldest and traditional form of water purification. All dissolved solids, suspended solids, and dissolved gases are removed.
Sometimes the distillation process is also referred to as the boiling process. In distillation, water is first boiled. and then when the boiled water condenses and leaves vapor, the vapor is collected in another container.
When the vapor condenses or cools down, it is turned into liquid. This cooled liquid is called distilled water and by using water distillers, you can produce this water easily. The other part of the water, which is impure, goes into another container. This impure water in the other container is the wastage water.
Distilled water is used in the electronic industry, automobile industry, and also medical industry. This water is also used for drinking purposes, but it is not recommended for a regular drink.
WHAT IS REMOVED AFTER DISTILLATION AND DEIONIZING PROCESS?
| Removes | Distilled Water | Deionized Water |
|---|---|---|
| Salt & Ions | Yes | Yes |
| Bacteria | Yes | No |
| Virus | Some | No |
| Organics | Some | No |
DIFFERENCES BETWEEN DISTILLED AND DEIONIZED WATER?
| No. | Distilled Water | Deionized Water |
|---|---|---|
| 1 | Uses boiling method, the vapor is condensed into a liquid | Uses ion-exchange method, where anion & cations are removed |
| 2 | Takes a lot of time to purify a large amount of water | Takes less time |
| 3 | Expensive method | Less expensive method |
| 4 | It filters out other elements and also removes harmful chemicals | It only removes ions and does not filter out other elements |
| 5 | Capable of removing impurities in water | Not capable to remove impurities in water |
| 6 | Water is very pure | Less pure water |
| 7 | Used in automobiles, laboratory, medical industry, etc. | Used in pharmaceuticals, laboratory, etc. |
| 8 | Also referred to as boiled water | Also referred to as demineralized water |
| 9 | Used for cleaning and sterilization purposes | Used in cooling applications and used in batteries |
| 10 | It’s okay to drink distilled water | Deionized water is not fit for drinking |
| 11 | Water is less corrosive | Water is highly corrosive |
| 12 | Has a longer shelf life | Cannot sustain if kept for long |
| 13 | Doesn’t react to CO2 | Reacts to CO2 |
| 14 | Requires high electricity usage | Requires less amount of electricity energy |
| 15 | Less environment friendly | More environment friendly |
SIMILARITIES BETWEEN THE TWO PROCESSES
- Both are pure forms of water
- Both use electricity to function
- Both are scientifically used
- Both are used in the laboratory and medical and other purposes
- Both can be used for drinking after the water is exposed to air for some time
WHICH IS THE BEST CHOICE – CONCLUSION
Both distilled and deionized water is pure water. Both serve the purpose, but both give different water results. What kind of purification one wants to use depends on multiple factors. Time, money, actual requirement, water needed for what purposes, etc., are few criteria to chose a purification system. On the whole, both are an old technique to purify water and have shown good demonstrated water results.
With so much information regarding purification systems can be confusing, but now we have destroyed all your confusion related to distilled and deionized water and given you enough information to make the correct choice. On this positive note, let’s end with a quote, “Water is the driving force of all Nature.” – Leonardo Da Vinci.
