boiled water vs purified water

Boiling water

Boiling water for purification is the oldest trick in the book. This time-tested method had been working great for us, till new technologies in water purification systems were introduced, to challenge its credibility. It is generally held that boiling water can kill 100% of pathogenic microorganisms present in the water, but this is not true. There are many mutated tough germs and super bugs which can be left unaffected in boiling water. Also, for killing germs dissolved in water successfully, it is essential to let the water boil for 20 more minutes after it reaches the boiling point; contrary to popular belief where people simply take the water off the heating stove as soon as visible bubbles are seen in the water.

Is boiled water purified water? The answer has to be No. To throw some light on this, here are some differences between boiled water and purified water which may highlight what limitations does boiling water for consumption have when compared to filtered water from purifiers;

  • Not only the boiling process may partially fail in removing the pathogenic microbes from the water, this purification process remains completely unaffected on the TDS, i.e. Total Dissolved Salts in the water. The higher the TDS, the harder is the water, and boiling cannot help soften the water or balance the acidity.
  • None of the dissolved impurities like dirt and fine metal particles like lead and arsenic is filtered out in this process. Dissolved chemicals like fluoride, pesticides, and chlorine, which might be contaminating the water due to extreme water pollution or improper treatment of water treatment, doesn’t evaporate on boiling. It simply heats and cools down.
  • Due to long boiling time, a lot of oxygen dissolved in the water is released in the form of bubbles. This gives the water a very flat taste.
  • The inactivated germs in the boiled water can reactivate themselves once the normal room temperature is obtained.
  • Utensils and hands if not cleaned properly, can lead to contamination of the water while handling, like when transferred from one vessel to the other.

Along with the limitations of the process, boiling water instead of using water purifier also poses inconvenience while handling the purification process;

  • Firstly, you cannot boil a lot of water in one go; limitations posed by your standard apparatus consisting of gas stoves and utensils. Hence you need to carry this process multiple times a day, repeatedly.
  • A lot of time is required for the water to cool down before it can be of useable condition.
  • Handling boiling water everyday multiple times increases the probability of one suffering burns and mishandling which the material.

Water Purifiers

The primary function of water purifiers is to filter out dissolved salts and chemicals from the water, like the RO water filters, and purify the clean water obtained from pathogens, like UF and UV water purification systems, which may otherwise lead to water borne diarrheal diseases. Where the tedious task of boiling water simply heats the water and merely reduces the probability of pathogenic contamination, water purifiers on the other hand can successfully filter out dirt, mud, chemicals, pathogens, fine metals and TDS from the water instantly, efficiently, at the normal room temperature, while not compromising on the dissolved oxygen levels of the water.

To conclude, if you wonder “Is boiled water safer than purified water?”, then the answer is not completely. We get better and efficient results from purifying water than boiling water. Still, if you prefer the boiling water purification method, it is advisable to filter out the water afterwards. Make sure you pass the boiled water through water filters after, and not before boiling it, since the water purifiers will successfully restore a balanced taste in the water.
