How Long To Boil Water To Purify (And Why)?

Exact Answer: In A Rolling Boil For At Least 1 Minute

Water is the most important substance to people, and it makes up 70% of the human body’s content; without it, one would not be able to survive for a long time. One way that water can become contaminated is by bacteria or other harmful contaminants which could make people sick. 

Luckily, there are simple ways to purify their water at home known to everyone. It boils the water to get rid of bacteria before drinking it. Boiling water is a great way to purify it for drinking.

The answer depends on what one is trying to accomplish. For example, if the goal is to kill germs and other microbes in the water, boiling it for just one minute will do the trick. Boil it longer than that, and it will start losing some of its healthy minerals like calcium, magnesium, and potassium.  

The first thing one needs to do is find a clean source of water that doesn’t have any dirt or debris in it. Then take the pot and fill it up about three-quarters full with the dirty water from the source. Next, put on a stovetop burner at high heat for roughly 15 minutes, so the liquid boils and evaporates all its impurities into steam until there’s nothing left but pure H2O.

The best way to make water safe to drink is by boiling.

Once done boiling the pot of drinking water, it’s important to let it cool before consuming because otherwise, burns may occur from hot liquid entering into one’s mouth, throat or stomach lining.

Clean water is essential for living a healthy lifestyle. But it has become difficult to trust tap water. That’s why many people are moving past boiling water to purify and are embracing the completely natural process of Kefir instead. 1 minute at a rolling boil will kill most bacteria and parasites in the water. 

Make sure to take the container off the heat after hearing small bubbles popping up from the bottom. Do not boil it again. One will want to shake or stir it, sit 15 minutes before drinking (although this isn’t necessary), and store it in a clean, dry, cool environment like the refrigerator or room temperature.

Boiling water is a way to remove impurities in the water by boiling them out of it. The process can take from one minute to an hour, meaning so much time depends on the purity of the water being boiled. Filtered and purified distilled water could be boiled for hours with no ill effects because it’s already pure before boiling starts.

 The boiling process heats the liquid to the boiling point, which is 100 degrees Celsius at sea level. If the liquid temperature were raised by 1 degree and not boiled over and brought back down, then it would take 10x that amount of heat energy to heat up again.

Boiling water will take a long time because it requires so much energy. That means if you’re cooking with 3 cups of water and boil at 100 degrees Celsius, it’s going to take a while after boiling to cool down.

Conclusion

It’s important to know how long one needs to boil water for it to be purified. The longer one boils the water, the more it will eliminate the contaminants. The boiling process is a simple and inexpensive way of purifying water when there are no other options that are as easy. 

Water that has been boiled should also have a pot cover or lid on top to reduce contamination during the cooling down period. Ultimately, bring the water to boil and keep it rolling for 1 minute to make it safe for drinking.
