Water filter

Imagine you have a cup of muddy water that you collected from a dirty pond. You can't just drink it straight away because it might make you sick. That is where a water filter comes in.

A water filter is like a magic wand that can turn dirty, unsafe water into clean, safe drinking water. It is a device that is used to remove harmful things from water, like bacteria, viruses, chemicals, dirt, and other impurities.

It is made up of different layers of materials that trap and remove different impurities from the water as it passes through. These layers can be made of things like charcoal, sand, and other natural materials, which act like tiny sieves, straining out all the unwanted things in the water.

When the water passes through the filter, it goes from being dirty to being clean and safe to drink. So, the water filter does an amazing job of making sure that the water we drink is pure and healthy for our bodies.
