How To Make A Homemade Water Filter

Another name for water is life. Without water, we cannot live. At the time of living or survival, there is no alternative to water.

A man can live a week without food, but without water, a man lives only 2 to 3 days. In an emergency period or the wildlife, this is very hard to get drinkable water.

If you have a water supply of your own, you can get fresh water in your emergency need. Here you will get the required information how to make a water filter.

How to Make a Homemade Water Filter

People typically do not know the way to make water fresh for fit for a drink by the water filter. So they cannot even think to make homemade water filtration system.

It is crucial to know the way to make a water filter for the emergency need.

Here you will know the necessary guidelines to make a water filter. The following are five easiest ways for making homemade water filtration system.

How to make a water filter science project in home

You can make a water filter with children using recycled materials available at home. The system is super for children in grades 3 through 6, but the benefit is that it works for all ages.

The construction of homemade water filtration system would take just about an hour. Testing of water filter depends on an hour to few hours for how fast water drips. Applying natural materials which mimic the water cycle of the Earth, children may learn the way of infiltration works and make a water filter that works well.

Homemade water filter materials

  • juice bottle or Plastic soda
  • tall drinking glass or Vase
  • small stones or Gravel
  • Activated Charcoal
  • Clean Sand
  • Cotton balls, coffee filter or small cloth
  • Water
  • Gardening dirt
  • Scissors or knife


  • Keep the bottle upside down to the vase or tall drinking glass.
  • Use a scissor or a knife to cut the bottom of an old plastic bottle or juice bottle
  • Keep cloth, cotton ball, or a coffee filter in the bottle of the first layer. The layer should be 1-2 inch thick.
  • Use an inch of activated charcoal to the second layer of the top of the cotton layer.
  • On the charcoal, use 2-inch gravel or small stone as the 3rd layers.
  • On the top add 3-4 inches of clean sand to the top of the gravel.
  • Add gravel with the final layer of the bottle. Keep half inch space from the top of the upside down of the bottle
  • Use dirt with the glass of water to make the water muddy. You can also add some other things like beads, glitter, cooking oil and some other materials to make the water dirty.
  • Pour a glass of muddy water to the top of the homemade water filter and see the water drip clean in the glass below.

Things you will need

If you like to make a homemade water filter, you need sand, gravel, activated charcoal or activated carbon, screen, five food graded five-gallon buckets, hole saw, plumbing fitting.

Bio-filter a homemade filter is made of 3 separate layers of gravels, activated charcoal, and sand.

It is the streamlined way of filtering impurities out of water beginning from the biggest to the minutest impurities in water.

Here’s How To Do It

  • Turn water gallon container to upside down
  • Make a hole in the top of the container. Here is the place you will pour minerals or water for filtration.
  • The first layer is made of gravel. The gravel is usually pebble like a rock which works like a filter for common debris found in the water like fallen leaves, small sticks and even little creatures which may be an animal or an insect. Then you have to fill the second layer with sand. Sand can filter out smallest particles from water which the gravel is failed to do so.
  • The 3rd layer is made of activated charcoal that removes minute impurities. Harmful chemical lingering or pathogens in water may be removed by carbon. The last three layers will make the water fresh and free from contaminants which process intended to eliminate.
  • Finally, this is a DIY carbon filter.

Making Other Types of Filters

Making Other Types of Filters

You can make cloudy water fresh by pouring it through the coffee filter. Take a round cut shaped coffee filter and then turn upside down to fit over a cup like a lid. After that, wrap a rubber band round the coffee filter to keep it in place. Gradually pour the cloudy water on the coffee filter. Finally, boil the water to fit for a drink.

  • If you have no coffee filter in the alternative, you may use a piece of cotton fabric or a paper towel. Be sure the square is large enough to fit over the mouth of the up. Then attempt to use a blank paper towel or fabric. Paper towels and colored fabrics contain dyes which can bleed in the water.

Use a banana peel to make a water filter. Fruit peel can absorb bacteria. At first, peel a banana and then grind the peel in a blender. You may discard the banana or eat it.

You may not need the filter. If the peel is blended for the first time, keep a coffee filter. Hold the filter over a cup.

Then pour water into the coffee filter. The peel of banana will absorb bacteria, and the coffee will make water clean again.

Prepare a plant xylem filter by using a water bottle as well as a pine branch. In sapwood, there is xylem that may absorb and filter out bacteria as well as dirt.

The capacity of it is to remove bacteria from water up to 99.9%.This also can eliminate virus like rotavirus and hepatitis.

You have to boil water after filtering to make perfect and safe for drinking. Under, there is a way to make a xylem filter.

  • Cut a four-inch long piece from a pine tree branch
  • Take out the bark; be sure it will fit the neck of the bottle. If it is very wide, shave it down by using sandpaper or a pocket knife.
  • Slide the first inch or of the stick to the neck of the bottle.
  • Cut the bottom of the bottle and turn it upside down
  • Pour water up to fill it and let the water drain inside the stick
  • Do not make it completely dry as it may not be effective more.


Why activated carbon? 

Activated carbon is the practical element of most filters. It’s essentially charcoaled that’s been treated to improve its potential for compound adsorption. It utilizes this procedure to generate water contaminants “cling” onto its surface and stop them from passing into your drinking water.


What you will need:

A plastic jar (the larger that will be the more water that your filter will be active at filtering per second)

  • Gravel
  • Sand
  • Activated carbon
  • Scissors

The quantities of this sand, gravel, and activated carbon are contingent on the size of jar you use. You will cut the base of the bottle away and fill it with layers of those materials.

What to do:

  1. To begin with, you will want to supply your stuff and prepare them correctly. Rinse the sand and gravel in water to be sure they don’t include any dust or dirt.
  2. Next, you must prepare carbon dioxide. Grind up the carbon into powder-like material.
  3. Together with the filtration media ready the following thing to do is make your jar. In theory, the higher the filtration media (gravel, sand, and activated carbon) which you employ, the higher the degree of water filtration you’ll receive. Additionally, note you will require a gap at the top where you fill the jar with water. The more distance on the very top, the more water you may place in the home-made water filter simultaneously.
  4. We can begin filling the jar with all the carbon, sand, and dirt. The sequence in which we place these in the pot is vital. We want the most massive objects in the very top and the smallest in the base. Don’t forget to make a gap of a few inches on top. This permits our water filter to fill up having a fair quantity of water every time it’s used.
  5. An additional tip to raise the potency of the home-made water filter would be to secure the jar cap. By placing a few holes at the jar cap, we could enable the wash water to pass but at a significantly slower speed. In other words, the water gets more contact time with carbon dioxide, which raises its efficacy at adsorbing pollutants. But, it will mean you are going to need to wait for more for your filtered water.

We finally have a good water filter that’s created from recycled materials and utilizes the very same techniques as many primary brand filters. This type of filtration is similar to some primary water filter pitcher but remember our homemade cleaner shouldn’t replace a professionally constructed and certified water filter.

This results in an enjoyable and educational science experiment that is ideal for young children. See what sorts of contaminants you may eliminate from the water.
