It is on this premise that we advise everyone should endeavor their water passes through the right filtering process before consuming. It is vital, mostly, if you reside in areas where the water quality is terrible.

So, getting a water supply is best, but what happens when you can't afford a decent water filter, or you are in a place without access to any of those tools. That's where a homemade water filter comes handy. However, not everybody knows how to make a water filter. In this article, we will bring you complete details on how to make a homemade water filter.

We will be taking it slow to ensure you grab every bit of information. So, follow us carefully.

Why Choose a DIY Water Filter?

Having a DIY water filter helps you save funds, and most of the tools that you need for it are available in your house. So, you are spending little to stay healthy.

hy Choose a DIY Water Filter

Also, having a homemade filter for water will give you more flexibility in filtering your water.

Have you ever wondered about a scenario where you are in a place without good tap water, and you are stuck? Water filter homemade becomes very valuable in such situations.

As a matter of fact, knowing a DIY water filter is valuable information anyone should have, and a lifesaver.

What We Don't Want in the Water

This is vital information you should process before deciding the type of water filter you want for your home. For water to be in its purest form, it has to be safe from every contaminant.

What We Don't Want in the Water

However, though water is a combination of both oxygen and hydrogen, it also contains some other necessary minerals which the body needs. For instance, most mineral water contains calcium and magnesium, which are beneficial to health.

Aside from that, all other chemicals which may be present in the water are contaminants and should be filtered away. Some of these contaminants are pesticides, industrial water, and other chemicals like chlorine. In some rare cases, you will also find viruses, protozoa, and bacteria.

Also, some other materials do not affect your health per se, but they play a harmful role in forming scales in your pipe.

In more severe cases, they may clog the pipe and hinder water flow. In such cases, you require water softeners to reduce the water hardness to the lowest minimum.

How to Make a DIY Water Filter?

Building a water filter is very easy if you desire to make one for yourself. But, there are different types you can pick from which we will be sharing, so choose wisely. Here is how to make homemade filters for water:

Bio Filter

Bio Filter

The bio-filter is a domestic system made up of three different layers: gravel, sand, and activated charcoal layer. It is a very efficient method of filtering out various sizes of particles, from large to very tiny particles.

Here's How to Do It

Preparing the system is straightforward; here are some of the required materials you need:

  • Screen, or mesh
  • Hole saw
  • Activated charcoal
  • Five food-grade five-gallon bucket
  • Gravel
  • Plastic plumbing fittings
  • Sand

Take the gallon, and turn it upside down. Cut a hole at the bottom to allow you to pour in the materials. Start by adding the rock, pebble, and then add the sand followed by the activated charcoal. The stones help remove particles and other insects. The sand helps to remove other smaller contaminants that the first layer cannot remove. The last segment, which is the charcoal, helps remove chemicals and other microorganisms that are left. Thus, giving you healthy drinking water.

At the outlet cap, ensure to put your screen or mesh, and place a water collecting bowl for collecting your filtered water. Also, when adding your materials into the gallon, leave some space for water that you will pour into the filter.

Also, you can add more materials if you desire, and you can even change the entire filtering process. The choice is all yours.

Distiller on the Stove

Distiller on the Stove

This is a very efficient form of water filtration. When set, it can turn-up both salty and dirty water into consumable water. Although it is quite technical to set up than other water filter DIY, it is a convenient tool to have, especially if you have devices that require distilled water or for consumption.

Here's How to Do It

Before starting this method, you have to prepare. You can start by getting the following required tools:

  • Glass bowl
  • Connecting valves
  • Kettle
  • Hose (stainless steel)

First of all, pour water into your kettle and place it on the stove or heat source. Then attach the stainless steel hose to the spout of the kettle and clip it with a connecting valve. Place the other end of the tube in your collecting bottle or glass bowl, then turn on the heat.

As the water boils, the evaporated steam will go through the hose, which will condense before arriving in your glass bowl as distilled water.

Take caution not to handle the hose before or after boiling to avoid hurting your hand. Allow the water to cool before storing it.

Improvised Charcoal Filter

Improvised Charcoal Filter

The improvised charcoal filter has a similar design to the bio-filter, only that you don't have to use sand. It is an excellent water distillation option, especially if you are outdoor, as charcoal is an excellent option for filtering water.

Here's How to Do It

Before we get started, here are some of the items you need:

  • Piece of cloth
  • Sand
  • 2-liter plastic bottles
  • Charcoal

Cut out the bottom of your plastic and turn it upside to in the form of a funnel. Then, cover the first narrow spout with a cloth. After that, break your charcoal into small pieces, to filter since it is the primary filter. Put the charcoal as the first layer before adding the sand on top of the charcoal.

Now your DIY water filter is ready. And all you have to do is pour in your water. If you want, you can alternate the charcoal and sand two more times for better filtration, but ensure to leave space to pour in your water.

Water from this system is cloudy and should be boiled again before consumption.

Boil Your Water

Boil Your Water

It is an easy filtering process and very straightforward. All that is required is for you to boil out impurities from your water.

But, boiling your water to remove impurities depends on the amount of water and the heat source.

Here's How to Do It

To boil your water successfully before drinking, you will need the following materials.

  • Water
  • Heat source
  • Pot

Pour your water into the pot, turn on the heat, and place your water in the container. When the water starts boiling, allow it to cook for three minutes more. You can get a timer to ensure this happens. After that, turn off the heat and allow the water to cool before storing.

You can leave your water to boil for more than three minutes, but that will not result in any further purification. Instead, your water will just keep evaporating. The more water you add, the more time it will take for your water to boil.

Solar Water Disinfection

Solar Water Disinfection

Solar water filtration is one of the most natural filtration methods to use, and an excellent choice for camping, picnics, and other outdoor activities. It is a location with lots of sunlight. The only disadvantage is that it can take a long time for the filtration to occur, although the source of the water also has a significant role to play.

Here's How to Do It

For this filtration method, all you require is just a container. Using a plastic airtight bottle,  gallon, or two-liter soda bottle will make it easier to save your water for later consumption.

Fill your preferred container with water and cover it with a screen to prevent contaminants from entering. Then, place it under sunlight.

If your water is bright and clean, then it is ready for drinking. However, it should stay for about two hours before you drink it. But if the water is cloudy, then you should leave it for two days, at least.

This type of water is not entirely clear, and you can filter before drinking, mostly if you don't have any other purification method.

Benefits of Having a Water Filtration System

Benefits of Having a Water Filtration System

Water, like oxygen, is vital for our daily living. And the contaminants in water can be life-threatening. However, water filters have come to alleviate this threat by removing chemicals, bacteria, and other pollutants in water. The benefit of a water filtration system is almost endless. However, here are some of the importance of water filters:

Healthier Water

It is the most essential and useful benefit of having a water filtration system. Most unfiltered water, even tap water, comes from a water treatment plan. However, they still contain some contaminants such as mercury, copper, arsenic, and so on. The water filtration system helps to remove these toxins and chemicals.


Using filtered water means you will be purchasing less plastic water bottles. So, you will be adding less plastic waste to the environment. It is crucial because plastic water bottles add more rubbish into the landfills, making it one of the top synthetic land pollutants.

Cost Saving

If you buy a plastic water bottle regularly, you will realize how much you have saved after installing a water filtration system. This is very true, especially if you have a family of four. Imagine how much you will be spending on buying water bottles, the price should be way more than it will cost you to install a water filtration system.

Improves Taste

Water filtration systems remove elements that cause your drinking water to have taste, such as chlorine, lead, and bacteria. Thus, it is more pleasurable to drink as it will improve the taste, smell, and purify the water. Water filtration systems also help to lower the pH level of your drinking water.

Reduce Plumbing Repair Bills

Having unfiltered water flow through your piping system may result in clogging of chemicals and particles which can block your pipe in the long run. Aside from that, it can also affect your home appliances and fixtures. With filtered water, you can curb these damage and lower plumbing repair bills.


During an emergency, like when sewer lines burst close to your house. It can result in water contamination. But, you will be protected if you have a water filtration system installed in your home.

Reduces Aggravated Skin Conditions

Having a water filtration system will reduce the risk of skin aggravating conditions caused by heavy metals, chlorine, and fluoride. Such skin conditions include eczema, psoriasis, and more, and they tend to affect kids the most.

Remove Soap Scum

In the long run, using unclean tap water will leave an unclean deposit on your clothes and smell funny. This is due to the chemical contained in them, which can also lead to rashes and allergies. They can also lead to soap scum buildup on your dishes and bathroom. However, having a water filtration system will remove the hardness of water, which is a significant cause of this problem.

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?

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.
