Which Is Better Boiled Water Or RO Water?
I have been doing a thorough clarification of the differences between both, talking with water technicians and others people involved in the water trade.
The result can be seen below:
The difference between boiled and RO water is related to the way they are produced because there’s no relevant chemical or physical difference regarding their composition. Both types offer an excellent quality level, according to specialists from the sector.
In this sense, Josep Maria Rivas, technical director at Rometa Water, tells us that “both types always guarantee a very high level of purity but there’s a slight difference due to the process through which they are obtained”. And he adds: “although usually only filtered water is used flavorings or coffee machines because it is the only one that guarantees a stable degree of hardness if it is necessary we can also use both types to obtain an excellent final product”.
For his part, Jose Antonio Millan, technical and quality manager at Millán de Olmos water company (southern Spain), agrees with Rivas. “Both boiled and RO water are very pure and purify well your machine but you should pay attention to which type you use because if you put in filtered or bottled water it could lose its properties as a result “.
Is boiled water safe to drink?
Josep Maria Rivas explains that “the boiled water is safe to drink but it has lost some of its properties due to the process”.
For his part, Jose Antonio Millan says: “Boiled water is not dangerous, it’s just purified water; however, if you use this type of product for your coffee machine you will need to descale it more frequently because its high mineral content tends to accumulate more deposits “.
Is there a difference between boiling and distilling?
Yes, experts agree on this point. “Distilled water is water that goes through a process known as ‘distillation’. And boiled or filtered one can also be produced through distillation” clarifies Josep Maria Rivas. However, he adds: “the difference is that in the distillation process water vaporizes, becomes lighter and rises to be condensed in another container; while the boiling process is achieved by heating water until it evaporates. ”
What’s more, Rivas points out that “distilled water has fewer minerals than boiled because when steam condenses they are deposited in the condensation chamber.” As Eladio Millán adds: “in this case, there will be no residue left”.
Which one can I use?
Water technicians agree with this question too. According to Josep Maria Rivas, both types of purified water (boiled or filtered) are suitable for coffee machines but you have to pay attention if you want to use one or another because some machines do not allow you to mix different types of water, so it is important that you know which one your equipment uses.
On the other hand, Eladio Millan emphasizes the fact that “the final product obtained will depend on which type of purified water you use: if with filtered or boiled one and there’s any particular flavor in the beverage then we can say that its taste is related to this factor”.
What is the highest quality water?
Water technicians agree in this case too. According to both professionals, high-quality water in addition to having an excellent degree of purity has the lowest mineral content possible because if you have a good filtration or distillation system but there are minerals left, then these will end up being deposited inside the coffee machine.
What’s the price difference between filtered and boiled water?
Both Romita Water’s technician Josep Maria Rivas and Millán de Olmos’ Eladio Millán point out that “the price difference is minimal or none”. When they are different brands bottled waters often contain more minerals than purified ones.
Finally, what should I keep in mind when buying water for my coffee machine?
Josep Maria Rivas recommends users to “keep in mind that it depends on the type of machine you have if it uses filtered or distilled water “. He also adds that “you should pay attention to which type of product is used because sometimes machines do not allow mixing different types of water”. On the other hand, Eladio Millán emphasizes that “the most important thing is the final result; if you use good quality purified water (filtered or boiled) with low mineral content your beverage will also taste better. And what’s more, this will extend the life of your equipment.”
How do I get the purest water?
Romita Water’s Josep Maria Rivas explains that “the process is very simple. With a filter, using a carbon cartridge, you can transform tap water into purest water.”
