Difference Between Distilled & Reverse Osmosis Water

Reverse osmosis and distillation are the most common and most effective water purification methods. Reverse osmosis is a water purification method wherein all water contaminants that are smaller than water molecules are removed. Distillation on the other hand wherein water contaminants are removed by boiling and the evaporated water is condensed back into a pure water to drink. Distillation is the oldest water purification method. Difference between reverse osmosis water and distilled water is not really obvious for some since they are both purified water. However if you look and study it closely, there is a huge difference between reverse osmosis water and distilled water.

Reverse osmosis and distillation, both are effective ways of water purification or filtration, but what is the real difference between reverse osmosis water and distilled water? 

Distilled water is safe to drink but it is usually used for research purposes where the purity level of water is very essential. Some baby milk formulas uses distilled water as the mixing liquid. Pediatric water or the water used for babies during a diarrhea outbreak is also made up of distilled water. Distilled water does not have sodium fluoride like any other kinds of water produced in different water filtration systems. Distilled water has flat taste like those of bottled water. Reverse osmosis water is considered mineral-free water. Reverse osmosis water are free from unwanted odors or odorless and it’s also colorless. Reverse osmosis water does not contain minerals that are dissolved unlike other water produced by different filtration systems. The system of reverse osmosis absorbs toxic chemicals making the water output fit for human consumption. Reverse osmosis water has no sulfates, arsenic, and aluminum. The taste of reverse osmosis water is one of the best attributes of this kind of water. Throughout the process of reverse osmosis, contaminant that makes the water taste unpleasant is removed. 

Whether it is reverse osmosis water or distilled water, they will always be safe drinking water. Difference between reverse osmosis water and distilled water does not actually matter since they both offer safe water to drink that gives benefits to the human body. Difference between reverse osmosis water and distilled water are cases which are not always noticed. Generally the only difference between reverse osmosis water and distilled water are the processes wherein the contaminants are removed but in the end, the output is the safe water that everyone wanted.


  1. The new Ultrsmeter III 9P is a great tool for process validation of RO systems. You can find it here:


  2. In the UK you can also get great value reverse osmosis units from http://www.clear-tech.co.uk/reverse-osmosis.html

  3. No doubt we need a quality water purifier for drinking needs, some water purifiers has reverse osmosis membrane filter which has pore size as small as to 0.0001 micron, so it can filter out the most contaminants, i recommend Coway water purifier.

    1. A great quality water purifier for drinking water, is the reverse osmosis system from Kinetico. I recommend this one!

  4. Drinking Water Filtration
    I all the time emailed this website post page to all my friends, because if like to read it then my friends will too.

  5. you can get more details about RO system by RamdounPURE www.rhkigl.com

  6. Water Spots
    Clued-up post! Your accepted wisdom is great. Thanks for keep me notify. For more information I will be in touch.

  7. best water purifier i've tried and i'm sticking to is berkey water filter. Instantly purifies water from any source including stagnant water.

  8. For over two years I ingested RO Water ONLY. Made coffee, tea, etc.. with RO ONLY. I transferred for my job, Boy was I Surprised. All the water at my new job Smelt like treated sewer water as well as tasted funny. Found out later , it WAS treated sewer water. People were used to it so did not notice the odor nor taste. The water was suitable for human consumption, according to water people who tested it for me. I've gone back to RO , my smeller works better, things taste better, I can do without the little extra" that is in city water, THANK YOU!!!!

  9. I had no idea the differences between distilled water and reverse osmosis water until reading this. Reverse osmosis seems to be a favorable process over distillation for the fact that water that comes from reverse osmosis tastes better. Thanks for posting this, it was very informational!
