How To Create A Water Filter At Home?

Looking to create your own water filter at home? Here’s a quick and easy guide on how to do it!

A water filter is a device which removes impurities from water by means of a physical barrier, chemical process or biological process. Filters cleanse water to different extents for purposes such as providing agricultural irrigation, accessible drinking water, public and private aquaculture, ridding household water of small particulates to reduce turbidity and protect plumbing, in swimming pools to keep them clean, and also for the safe use of reclaimed or recycled water.

What you will need

In order to make a water filter, you will need the following materials:
-A pot
-A bottle

1.Layer the charcoal, sand, and gravel in the pot.
2.Place the cheesecloth over the top of the pot.
3.Pour water into the pot.
4.Allow the water to filter through the layers and collect in the bottle below.
5.Enjoy your clean, filtered water!

Step one: gather your materials

Creating your own water filter is a simple way to make sure that the water you and your family drink is clean and safe. It’s also a great project for kids to help with, as it requires few materials and is not too complex. Follow the steps below to create your own water filter at home.

What you’ll need:
-A clean 2 liter soda bottle
-A coffee filter or paper towel
-Activated charcoal (you can find this at most hardware stores)
-A small rock or pebble
-Clean sand
-A knife or scissors

1. Cut the top off of the soda bottle, making sure that the cut is even.
2. Fold the coffee filter in half, and then half again, until it is about 4 inches square. Tape this to the inside of the bottle top so that it hangs down into the bottle. This will be your filter.
3. Pour 1/4 cup of activated charcoal into the bottle. You can add more or less depending on how much you want to filter at one time.
4. Add a small handful of rocks or pebbles to the bottle on top of the activated charcoal. These will help break up any clumps in the charcoal and allow water to flow more easily through the filter.
5. Pour 1/2 cup of clean sand into the bottle on top of the rocks or pebbles. This will help catch any smaller particles that made it through the activated charcoal and rocks/pebbles.
6 screw the bottle top back on, making sure that the coffee filter is secure so that nothing can fall out when you turn it upside down

Step two: cut the bottle

Creating a water filter is easy and can be done with materials you likely have around your house. All you need is a plastic bottle, a coffee filter, and some gravel. This simple filter will remove any sediment or large particles from the water, but will not remove bacteria or viruses.

To start, cut the plastic bottle in half using a sharp knife. If the bottle is too difficult to cut, you can score it first with the knife. Once the bottle is cut in half, remove the top half of the bottle. This will be the container for your filtered water.

Next, cut a coffee filter to fit snugly inside the bottom half of the bottle. Make sure there are no gaps around the edges of the filter.

Now, add gravel to the bottom of the bottle until it reaches about 1 inch from the top of the bottle. Slowly pour water into the bottle on top of the gravel. The water will filter through the gravel and coffee filter as it trickles down into the top half of the bottle. Allow all of the water to filter through before removing the top half of the container

Step three: make the charcoal

To make the charcoal, you will need:
-A large pot or crock pot
-1 pound of unopened, raw hardwood charcoal briquettes (do not use the self-lighting kind that has chemicals in it)
-A metal or glass bowl that fits inside the pot
-A wire mesh screen or coffee filter
-2 quarts of water

1. Soak the briquettes in 2 quarts of water for 30 minutes. This will help to remove any chemicals that may be on them.
2.After 30 minutes, drain and rinse the briquettes.
3. Place the bowl upside down in the pot.
4. Place the briquettes on top of the bowl in the pot, making sure that they are not touching the sides or bottom of the pot.
5. Cover the pot with a lid and turn it on to low heat.
6.Let it cook for 3-4 hours, or until the briquettes are black and have stopped smoking.
7.Once they are done, turn off the heat and let them cool completely before handling them.
8. Once they are cooled, put them in a blender and blend until they are a fine powder.
9. Pour the powder through the wire mesh screen or coffee filter to remove any large pieces that didn’t get pulverized by the blender.

Step four: make the sand

Now that you have all of your materials, it’s time to make the sand. This part is simple: just add 1 cup of sand to your container. If you want to, you can add a little bit of water to help the sand settle.

Step five: make the gravel

The final step in making your water filter is to make the gravel. This will help to remove any remaining impurities in the water.

To do this, you will need:
-A clean, empty plastic bottle
-A coffee filter
-A funnel
-A small piece of cloth
-A rubber band
-A knife
-Some gravel

1. Cut the bottom off of the plastic bottle with the knife.
2. Place the coffee filter over the top of the bottle neck, and secure it in place with the rubber band.
3. Place the small piece of cloth over the top of the coffee filter.
4. Pour the gravel into the bottle slowly, using the funnel. You should fill the bottle about half full with gravel.5 5. Now it’s time to test your water filter! Pour some dirty water into the top of the bottle, and watch as it drips through into the clean water below.

Step six: put it all together

Now it’s time to put all your newly made materials together to create your very own water filter. Depending on the size of your container, you may have to adjust the amount of each element you use. The following is a guide on how to put your water filter together.

-Start by placing the gravel in the bottom of your container.
-Then add the charcoal on top of the gravel.
-Next, place the sand on top of the charcoal.
-Finally, top it off with the cloth.

Your water filter is now complete! Be sure to test it out before using it to filter any water you plan on drinking.

Step seven: test your water filter

Now that you have completed your water filter, it’s time to test it out. Fill a clean container with water from your tap and pour it through your filter. Then, take a sample of the filtered water and compare it to the unfiltered water. You can do this by testing the pH balance or by sending a sample of each to a lab for analysis.

If your filter is working properly, the filtered water should be clean and clear. It should also have a slightly different pH balance than the unfiltered water. If you are unsure about whether or not your filter is working properly, send a sample of both the filtered and unfiltered water to a lab for analysis.


After testing your water filter, it’s time to install it. The process is easy and only takes a few minutes.

1. First, find a clean, empty 2-liter bottle.

2. Cut the bottom off of the bottle using a sharp knife or a box cutter. Be sure to cut below the curve of the bottle so that the base is flat.

3. Invert the top half of the bottle and insert it into the bottom half. The snug fit will keep the two halves together.

4. Put charcoal in the middle of your filter. You can use either activated charcoal or regular charcoal from your backyard grill. Break up the charcoal into small pieces so that it will fit easily into your bottle.

5. Fill the remainder of your filter with sand. Be sure to use clean sand that has been washed free of chemicals and pollutants.

6. Place yourfilter in a location where you can easily access water for drinking, such as a kitchen sink or bathroom sink. When you’re ready to use it, simply pour water into the top half of the bottle and let it filter through to the bottom half
