Water filter

 is a simple device created with basic materials to help clean dirty or contaminated water. These filters remove impurities such as sand, small particles, and some microorganisms. Although they do not make the water 100% safe for drinking, they are useful for educational purposes, emergencies, and understanding how filtration works.

What are they for?

Homemade water filters are used to improve the clarity and quality of water. They help remove visible dirt, bad smells, and some contaminants. They are commonly used in science projects, survival situations, and places where clean water is limited. Their main purpose is to demonstrate how filtration systems work in a simple and affordable way.

Materials commonly used:

Plastic bottle or container

Gravel (small stones)

Sand

Activated charcoal (helps remove odors and some impurities)
