A natural water filter made from water purification homemade parts

The water filter is made of water purification homemade parts. The water filter removes contaminants from water by using a process called “adsorption”. This process uses the surface area to hold onto water molecules and other substances like dirt, bacteria or viruses. It’s not complicated, it’s just physics!

Materials Needed

Supplies Needed:

  • Plastic bottle or comparable food-safe container
  • Another container for clean water
  • Clean cotton or cheese cloth
  • Coffee filter or porous cloth
  • Charcoal
  • Sand (fine and coarse)
  • Gravel or pebbles

1 – Remove the bottom.

Cut off the bottom of the bottle you’ll be putting the filter material in with scissors or a knife.

2 – Make a drain hole

Make a small hole in the cap with scissors or a knife. If there is no cap, cut off the top of the bottle rather than the bottom for the previous step, and then poke several small holes in the bottom of the bottle.

3 – Straining Fabric, 1st Layer

Fill the bottle halfway with a fine cloth or paper fabric, such as a coffee filter, cheese cloth, or cotton stuffing.

In this first stage, sand and grass can also be used. Fill the bottom with about 3 inches of grass clippings to filter out larger particulates and provide a clean taste to the water from the chlorophyll in the grass. Then add 3-4 inches of very fine sand.

When collecting grass clippings, take care not to use poisonous or unidentified weeds. Avoid using Highway Department sand because it may contain road salt and chemicals.

4 – Separate the Charcoal

Use a hammer or rock to break down the charcoal from a campfire or BBQ charcoal (do not use match/instant light type because it is soaked in chemicals) into the smallest particles possible.

5 – Second Layer: Pulverized Charcoal

Fill the bottle with about 3 inches of pulverized charcoal. Cover with another coffee filter if one is available to prevent the charcoal from being displaced too much during the filtering process.

6- 3rd Layer: Fine Sand

Add a layer of the finest sand you can find, about 2-3 inches thick. This layer, along with the subsequent layers, will filter out particulates in the water.

7 – Coarse Sand (fourth layer)

Add a layer of coarse sand or very small pebbles, about 2-3 inches thick.

8 – 5th Layer Fine Sand

Add an additional 2-3 inch layer of the fine sand. Multiple varying filter stages (like a reverse osmosis system) ensures that most of the particles present in the water are caught.

9 – 6th Layer: Gravel

Add a 2-3 inch layer of gravel or small rocks to prevent the water being poured in from displacing the sand.

10 – Top Strainer

Cover the top of the filter with a porous cloth, such as a bandana or cheese cloth. This step is optional, but it is useful for straining large debris from the water and preventing the pouring from displacing the sand inside the filter.

11 – Pouring & Gathering

Slowly pour water into the filter while holding it over the second container.

Make sure to clean or wipe down the collection container. Pour water slowly to avoid disturbing the filter layers too much or causing the filter container to overflow, potentially spilling unfiltered water into the collection container.

12 – Sanitize the Water

Even after filtering the water through many layers, microbes can still exist in the water, and it must be sterilized. The simplest method is to boil the water in a pot or kettle.

Sunlight can also be used to sterilize water. Fill a clean, clear plastic or glass bottle 3/4 full with filtered water and screw on the cap. Shake the water for thirty seconds to add more oxygen. In direct sunlight, place on a light or reflective surface. The amount of exposure required is determined by the weather. A clear day necessitates 6 hours of exposure, whereas 50% or more cloud coverage necessitates 2 days of sunlight.


Using water purification homemade parts, you can create a water dispenser in Singapore that will help to improve the quality of your water. With just a few materials and some time, you’ll be able to provide cleaner water for yourself and your loved ones! This is an easy project with affordable supplies–a great way to get started if DIY projects are new territory for you. You may want to compare prices on different types of sand before purchasing so that you purchase only what’s necessary without wasting money or resources in the process. If this seems like something worth doing at home with little effort.
