Both reverse osmosis water and distilled water can provide high-quality pure water, but many people don’t know which one to choose. This article will explore the differences between reverse osmosis water and distilled water to help you choose.
What is reverse osmosis water?
Reverse osmosis water is a kind of pure water treated by reverse osmosis (RO) technology, which only allows water molecules to pass through and can block most pollutants. For example, impurities such as dissolved salts, organic matter, suspended matter, etc.
The reverse osmosis membrane is a semi-permeable membrane that only allows water molecules to pass through. When tap water is pushed into one side of the reverse osmosis membrane under high pressure, water molecules pass through the membrane, while other impurities are retained on the other side of the membrane. In this way, water with higher purity is obtained. Reverse osmosis water is usually used for cooking and drinking and can be suitable for outdoor and home use.
Advantages of reverse osmosis water
- High purity: Reverse osmosis water can remove more than 99% of impurities, with a high purity close to distilled water.
- Good taste: Reverse osmosis water has no odor, tastes sweet, and meets drinking standards.
- High safety: Reverse osmosis water can effectively remove harmful substances such as bacteria and viruses in water, making it safer and more hygienic.
- Wide range of uses: Reverse osmosis water can be used for drinking, cooking, beauty, washing, fish farming, flower farming, and many other occasions.
What is distilled water?
Distilled water refers to pure water prepared by distillation. It can be distilled once or multiple times. It is to heat water to boiling, make water vapor rise, and then cool the steam to condense into water, thereby removing most of the impurities in the water.
Distilled water is widely used in medical treatment, scientific research, production, and life.
Advantages of distilled water
The production of distilled water is to boil the source water to evaporate and condensate recovery, to consume a lot of heat, the cost is very high, for the production of distilled water in the source water of other heat evaporation substances, also with the generation of distilled water and condensation into distilled water.
Such as phenols, benzene compounds that are harmful to health, and even mercury that can be evaporated. To obtain pure water or ultra-pure water, it must be twice and three times distilled, and other purity means must be added.
But the distilled water on the market for drinking can't do that. At the same time, regularly drinking distilled water is equivalent to giving up 5% of the source of trace elements that the human body needs from water.
The distilled water device in the laboratory is the tap water heated by electricity to boil, and the vapor is condensed into distilled water through the condensing pipe, which is collected.
What's the difference between them
Performance comparison
Reverse osmosis water can remove more than 99% of impurities, and can also remove most dissolved substances, while still retaining some minerals.
Distilled water is extremely pure and can remove almost all impurities. It calls it one of the purest waters.
Price comparison
Distilled water requires heating the water to a boil, consuming a lot of energy. In mass production, the higher the energy consumption, the greater the cost.
In general, the price of reverse osmosis water purifiers is still cheaper than distilled water.
Convenience comparison
Distilled water requires the purchase and maintenance of distillation equipment, which is relatively troublesome to use and consumes a lot of electricity. But it is more suitable for special occasions that require high-purity water.
If a family wants to obtain pure water through reverse osmosis, it needs to install a reverse osmosis system, which is very convenient once installed. At the same time, outdoor access can be achieved through portable design reverse osmosis water purifiers. Compared with distilled water, reverse osmosis water is more convenient to obtain and use and is more suitable for daily drinking.
Distilled water and reverse osmosis water both provide high-purity water, but each has its advantages. Distilled water is known for its extremely high purity, but the price is relatively high and the use is not as convenient as reverse osmosis water. The reverse osmosis system provides pure water for home and outdoor users because of its economical and easy-to-operate advantages. However, whether you choose reverse osmosis water or distilled water, you need to decide according to your needs and preferences.

How to choose between reverse osmosis and distilled water?
First of all, both are very pure water. But they are purified by different methods. Which one to choose depends on personal needs and preferences:
Purity
Distilled water is extremely pure, while reverse osmosis water is also very pure, but it retains some minerals compared to distilled water.
Taste
Distilled water is very pure and tastes slightly bland because it removes minerals from the water.
Compared with distilled water, reverse osmosis water is sweet and slightly mineral and usually tastes better because it may contain some minerals. Therefore, reverse osmosis water is very suitable for drinking tea, coffee, etc.
If you need the highest purity water, such as for scientific experiments or medical equipment, then distilled water is a better choice. If you are looking for reasonably priced drinking water that tastes better than distilled water, then reverse osmosis water is a good choice.
Therefore, when you choose water treatment equipment, you need to consider branded water filtration systems, such as ITEHIL reverse osmosis water filtration systems, which have a complete after-sales service system and portable design, and are deeply loved and praised by consumers.
Conclusion
In summary, both reverse osmosis water and distilled water are high-quality sources of pure water. The final choice depends on your specific needs and preferences. Distilled water is the ideal choice for the ultimate purity. And reverse osmosis water has achieved a better balance between taste and economy. I hope that the analysis in this article can help you make a wise choice and enjoy high-quality drinking water!
Frequently Asked Questions
Which is better purified water or reverse osmosis water?
Pure water usually uses multi-stage filtration to remove impurities such as mud, rust, and bacteria. But its purification process is very mature and the price is very affordable. Reverse osmosis water uses reverse osmosis membrane technology to filter out heavy metal ions, pesticides, etc. in the water, and its purification is higher. Therefore, whether it is purified water or reverse osmosis water, they are both suitable for outdoor and daily home drinking.
Is it better to drink tap water or reverse osmosis water?
First of all, it depends on the taste and health of the water quality in your area. Although tap water is strictly treated by the water plant, there are still residual chlorine and heavy metals, which will seriously affect the taste of the water. Reverse osmosis is a strict purification system that can filter out most of the impurities in the water. Due to concerns about pollutants, more people may choose to drink reverse osmosis water.
Does reverse osmosis water hydrate you better?
Although reverse osmosis water is popular because of its high purity, its effect of replenishing water is not fundamentally different from other drinking water. The essence of water is H2O, and no matter what kind of purification method is used, it can play the role of replenishing water.
The amount of minerals in the water has little effect on the body's water absorption. The body mainly gets the minerals it needs from food, not drinking water.
