Contaminated drinking water is a huge hazard. It could cause a whole lot of health issues and diseases. Since water is a major part of human existence, it is necessary to drink only pure water at all costs. You need to know how to purify your water before using it for different purposes like drinking, brushing, cooking, washing, and so on. There are several ways in which you could purify your water at home. They are easy steps that you need to follow before using the water for household uses. Quaility Water Purification

An important thing you need to keep in mind before purifying water is that most water filters do not purify water. The main job of water filters is to filter water, and that is it. They only clean it, and that is not enough for your uses. Water that looks clean could also be contaminated with bacteria, viruses, and other contaminants that could cause illnesses. So, it is important that you clean water and also purify it.

Water Purification

Once you get clean water, you need to purify it. There are a number of methods you could use for it. Here are some of the most popular water purification methods to get pure drinking water at home.


Boiling is the most popular water purification method used in every household. Bring clean water to a boil and keep it at a rolling boiling for a time of 10 minutes. At higher altitudes, the boiling time must be increased. This is because water boils at a lower temperature in places at higher altitudes. This makes it less effective for purification. The case is even more significant if the altitude is more than 2000 metres.  For more reliable results, you could even go for a second purification method. boil-water

Serious dehydration problems could be caused even due to mild cases of diarrhoea and other illnesses. So, it is important to exercise utmost care. Use a kettle or put a lid on top of the vessel while boiling water. This helps by keeping the heat inside the vessel and making the water boil faster. As such, lesser fuel will get consumed in the process. You could even use another pot or a tinfoil as a lid in case you do not have a teapot or a lid for the pot that you are using.

Once the water is boiled, you need to let the purified water sit for a while and cool down before drinking. When you transfer this water from the pot to your water container, be sure to avoid contaminating the top of your water.

Bleach or Chlorine

You get to buy small bottles of chlorine dioxide tablets. They are compact and can be directly used for water purification. Leave the water for 4 hours so that the tablet dissolves completely. You could shake it occasionally to speed up the process.

Using liquid bleach helps in a faster process. It is simpler and less costly than the tablets. Be sure not to use the scented ones, as they render the water unsuitable for drinking purposes. Use only regular bleaches.


Iodine tablets and tincture of iodine are commonly used for water purification. It is not as effective as chlorine, but yields satisfactory results. potassiumiodidepills13

An important thing to note here is that pregnant women should never consume water that has been disinfected using iodine. Same is the case for people with thyroid problems or those who are known to have hypersensitivity towards Iodine. You must never use Iodine treated water continuously for more than a few weeks.

Hydrogen Peroxide

Peroxide works similar to iodine and chlorine. An issue with this method is that hydrogen peroxide degrades very quickly. This is especially when the container has been opened previously. So, this method must be used only if the others are not available.

It is not possible to give accurate dosing information as the strength of peroxide declines even in an unopened bottle. You must never drink hydrogen peroxide straight.


Wine has been used as a purification method since ancient times.  It has been found that mixing 1 part of red wine to 3 parts of water could t=yield a limited level of purification. Bacteria are killed by this method. This treatment must be viewed as the last resort only.

Stabilised Liquid Oxygen – Activated Oxygen

Iodine and chlorine could cause health problems if they are used for a prolonged period of time. This problem can be avoided by using activated oxygen. Moreover, it has no effect on the taste of the treated water.

This is a lesser known treatment method that is hard to find locally. You could find it in health stores or homeopathic stores.

Salt Water – Desalinization or Distillation

You must always remember to never drink salt water. Even if you only have sea water available, you must remove the salt and purify it before drinking. Boil the salt water, catch the steam, and then let it condense in to water as it cools. This is effective if you do not have the equipment for distillation. This is the only way you could remove the salt from water. Even expensive filters could not remove salt from water. unnamed

One thing to keep in mind is that distilled water is not healthy for long term use as drinking water. So, you must never use it for prolonged periods of time.
