Humans are made of water. Around 60-70% of the human body is just pure H2O. Due to its chemical properties, water is responsible for regulating vital body functions. It acts as a main component of body fluids, is responsible for transporting nutrients and waste products, assisting in chemical reactions and regulating body temperature, etc.
Every cell in human body needs water to function properly. That is why regular hydration throughout the day is essential to stay in good health. Everyone knows how important is to drink at least 1.5 liters of water per day. However, what is very confusing to most of us is WHICH WATER IS BEST TO DRINK.
The saying goes: “you are what you eat” but here at Greenwave we believe in “YOU ARE WHAT YOU DRINK!”
When it comes to the water that you are drinking, making the right choice is really important. In this article we are going to investigate the differences between distilled, mineral and purified water to find out which one is the best fit for you and your family.
Distillation process (often with necessary pre filtration） removes everything from the water, both good and bad things. The process relies on the difference between boiling points of water and other harmful components that may be in the water. Through distillation, water becomes vapor, leaving the other harmful components behind. The vapor is cooled down when it passes through the pipe and then is collected after returning to its liquid state, but in much purer form.
After describing the process, we would like to destroy the myth. Drinking distilled water is not harmful! However, some sources claim that distilled water leaches minerals from your body and could put your health at risk. Is this true?
So distilled water doesn’t provide you with minerals that you get from tap water- for example Calcium and Magnesium that are responsible for hard water. Since it doesn’t contain its own minerals, some people worry it has a tendency to pull them from whatever it touches to maintain a balance. However, human body is a natural balanced system which will not be influenced that much by the pure water. Besides, you already get most of the minerals from your food, fruits and vegetables. Depending on where you live, distilled water could be better for you than tap water. If your town’s water is tainted with harmful chemicals or pesticides, distilled water is an obvious choice. Additionally, you might not be a fan of its taste because it is rather flat and… tasteless. Yes, pure H2O doesn’t have any taste!
Mineral or spring water
It is a good option for drinking and providing good nutrients to the body. However, it’s important to check the authenticity of spring water, as only 55% of the bottled water that claims to be spring water actually is bona fide spring water. 45% is just treated tap water. This does not give us the same benefits, nor will it have the refreshing, unique taste that real spring water has.
Please note that the temperature of water you consume is important as well. It is not recommended to boil mineral water for tea, coffee or drinking becsise during boiling the minerals will turn into the sediment at the bottom of your kettle, so you will not benefit from the minerals consumption. People with kidney stones should avoid mineral water and switch to distilled or purified drinking water from the RO system. Tap water or roughly filtered water are not good options for people with kidney stones either.
Purified water mainly refers to water that went through the Reverse Osmosis (RO) based purification systems, and also refers to the purified bottled water made of the regular tap water that went through similar type of purification though in larger scale. This type of bottled water is the most popular in the market. Water purified by RO system is much cleaner compared to water that went through other types of filtration such as activated carbon or ultrafiltration systems.

Purified water has low total dissolved solids content, close to distilled water, and has almost no minerals in it. Though some factories might add artificial minerals inside the bottled water, the fact is the minerals content in the bottled water is still insignificant compared to what a recommended daily intake.
Which is more suitable?
There is no one-size-fits-all approach for choosing the best type of drinking water. There are many factors to consider: quality of tap water where you live, purification systems in place, health conditions and taste.
Water taste and cost
Natural mineral water is often tasting better than purified water and distilled water, which also is the more costly choice, especially for these imported from abroad. Between distilled water and purified water, distilled water is sold generally at a higher price for the higher production cost than the purified water.
Meeting cooking needs
Boiling does not make unclean water clean. For health's sake, it's better for consumers to use drinking water for cooking. Among the 3 choices, natural mineral water is the least recommended option as it's expensive and not suitable to be boiled. Distilled water and purified water will be good choices for meeting the needs. Please keep in mind that you will need much more water for cooking than for drinking, so it worth considering the costs.
Besides the above factors, what to consider is about the health effects. Water in the bottles is not necessarily healthier than tap water. In addition to the fake water which poses potential risk for users, the reported new finding about millions of plastic particles found in the bottled water are worth for user to read and be aware of.
“Bottled water is marketed as though it's cleaner than tap, but numerous studies show it's definitely not cleaner,” “Based on all the data we have, you're going to be drinking significantly less plastic from tap water out of a glass than if you go and buy bottled water.” 瓶装水在市场上被认为比自来水更干净，但许多研究表明它绝对没有那么干净。“根据我们掌握的所有数据，与购买的瓶装水相比，自来水中的塑料量要少得多。”

Safe and sustainable water choice
No matter it's spring water, distilled water or purified water, the production, transportation and delivery of the plastic bottles from the factories to end-users will consume a lot of energy and generate a lot of plastic waste. The whole process is not sustainable at all while adding to comparatively high cost. There is some better option.
At Greenwave we support sustainability efforts in the water sector, and we want to help companies and individuals reduce carbon footprint and waste generation while securing the drinking water. By using proper purification systems, users could get portable water out of the running taps. There could even be available through rental options.
