15 Proven Methods to Purify Water for Drinking (Detailed Guide)

How to purify water?

Water is very vital to our health. But what do we do when the water at home is full of soluble impurities, sediments and germs?

Here are 15 proven methods to make clean drinking water at home.

Each method is useful for removing certain impurities.

You can use any combination of these to remove all kinds of impurities from the water.

Purify water by boiling

Boiling water is perhaps the most common and well-known way to purify water at home.

This is because it’s really simple to do and very effective at the same time.

To do this:

  • Place a pot or similar utensil on a stove

  • Fill it with water

  • Heat it until it starts to boil

  • Leave it boiling for around 10 minutes

Using heat to boil the water ensures that any germs are killed. This method is not very effective at removing solid impurities, however.

Purify water with bleach (chlorine) to kill pathogens and viruses

First, a warning - Bleach is poisonous in large doses!

Even so, using a very small amount of bleach can help kill bacteria and viruses in the water.

This works because the chlorine present in the bleach is particularly harmful to the germs in the water.

To safely purify water using bleach:

  • Fill water in a flask or other glass utensil

  • Add 4 drops of bleach per litre of water

  • Stir the mixture

  • Wait upto an hour before drinking the chlorinated water

We do not recommend this method of water purification as there are other ways you can make clean drinking water by following the guide.

Purify water with iodine to kill germs

A few drops of iodine can kill germs just as effectively as bleach.

To do this:

  • Fill water in a flask

  • Add 4 drops of iodine solution per litre of water

  • Stir the mixture

  • Let it sit for 30 minutes to an hour before drinking

This method is the safer alternative to using bleach, but it can give an unpleasant taste to the purified water.

We do not recommend this method if you’re pregnant.

Purify water with charcoal

Hard charcoal, or activated carbon as it’s called sometimes, is very effective at removing hard impurities, chlorine and also improves the taste and odor of impure water.

It also retains the minerals in water which are important for our health.

To purify water with charcoal:

  • Firstly, clean the charcoal sample with running water or boiling it. Then drain the water and let the charcoal cool (around 10 minutes).

  • Fill the impure water in a glass or ceramic container

  • Carefully place the cooled charcoal (100 gm per litre) into the container filled with water

  • Cover the container (use a cloth if there’s no lid)

  • Let the container sit for a day or two

  • Pour the clean drinking water into a flask or bottle

Purify water with sunlight

What do you do when you’ve got nothing but a bottle of impure water and it’s noon time?

You use the sun of course!

Using sunlight is an easy and eco-friendly way to kill germs in water. The only trade-off here is time.

  • Fill a bottle with water and seal it tightly

  • Place the bottle on its side under direct sunlight

  • Leave it outside for the whole afternoon (around 6 hours)

It really is that simple. Just be sure you’re not thirsty until the evening...

Purify water with moringa seeds

Moringa seeds have many health benefits and are cheap to buy.

Turns out they’re also efficient at purifying drinking water.

It’s a pretty long process, but can clean muddy water filled with sediments and dissolved impurities:

  • Take the dried seeds and remove the husks

  • Crush the kernels (inside of the seed) into a fine powder

  • You’ll require around 100 mg of powdered seeds to clean 1 litre of water

  • Mix the powder with a small sample of clean water

  • Strain the solution through a piece of cloth to obtain a milky fluid

  • Mix this fluid with the impure water by stirring quickly for 30 seconds, then slowly for another 5 minutes

  • Let the mixture settle for half an hour (keep the container covered)

  • Pour the clean drinking water into another container

Purify water with disinfection tablet

A disinfection tablet contains chlorine or some other chemical agent to kill germs in water in a couple of hours.

A single tablet is enough to cleanse a litre of water, so these are really handy.

The process is really simple:

  • Take a liter of water to be purified

  • Drop one tablet into the bottle/container

  • Wait for a few hours for the disinfection to be effective

Purify water with cilantro

Cilantro leaves are very effective at removing nickel and lead and some other heavy metals from water.

They’re easy to obtain and you only need a small bunch of leaves to do the job.

  • Fill water in a flask or jug

  • Immerse the leaves in the water and stir it for a few minutes

  • Leave it to sit for an hour

  • Remove the leaves from the pitcher

Purify water with pine stem

Pine stems have powerful disinfecting properties and can kill germs present in water.

For this method, remove a branch from the pine tree. Then:

  • Peel away the bark so the sap is visible.

  • Place the stem inside a container or bucket

  • Pour the impure water slowly along the stem into the bucket

  • Remove the stick and pour the purified water into a flask or jug

Purify water with clay pot

Clay is a porous material that can filter out minute impurities like sediments and even some germs.

Using any clay utensil:

  • Pour water into the utensil

  • Place the utensil on top of a pitcher

  • Let it sit there as the water trickles down slowly

This method can take hours to purify the water, so we’d recommend trying other methods if you don’t like waiting for clean drinking water.

Purify water with homemade filter

If your drinking water has large sized impurities, the easiest method is to make your own sediment filter at home.

Watch the video below for a simple step-by-step process you can follow:

Purify water with cloth

Another easy way to remove large sediments from water is to use a piece of cloth.

It is preferable to use cloth made of silk, since it is not too flexible and is also made of thin interwoven material. This is useful for catching the impurities and filtering out the clean water only.

  • Fill a container with the impure water to be filtered

  • Cover the opening tightly with a silk cloth

  • Invert the container onto a bigger container

  • Let it sit until all the water has been filtered

Purify water with cactus gel

If you manage to obtain a piece of cactus flesh, it can be used to disinfect water.

The gel inside the cactus has special properties that can remove not just some bacteria, but also metals like Arsenic.

To do this efficiently:

  • Place the cactus flesh inside a pot

  • Pour water into the pot

  • Boil the water for 10 minutes

  • Remove the cactus flesh from the pot

Purify water with UV flashlight

A UV flashlight can be used to quickly remove germs from drinking water. This is useful especially when you’re outdoors in the wild.

Just point the UV beam into the water you want purified and let it cover the water sample thoroughly for a few minutes.

UV light is very harmful to bacteria and viruses, so it is an effective method to purify infected water.

Using a water purifier - the most effective method

To completely purify the water, a combination of the above methods is required. This can take a lot of effort and consumes a lot of time to purify a small amount of water.

Using a water purifier, you can automate the entire process and have clean drinking water at any time of the day,

This is why we recommend a fully equipped water purifier that can handle all kinds of impurities efficiently.
