Water is filtered because unfiltered tap water can and does contain lead, chlorine, chloramines, VOCs and more in the water. Getting a good quality filter will ensure these contaminants are not dangerous to your long-term health.

Water is typically filtered through a series of physical and chemical processes to remove impurities. This can include sedimentation, filtration through materials like sand or activated carbon, and disinfection using methods like chlorine or UV light. These processes help to trap and remove contaminants from the water, making it safe for consumption.

For a science fair project, my friend and I, made a homemade water filtration system. what we did was....

1. bought coal bits, pebbles, sand, and rocks

2.we drank 4 2 liter bottles of sparkling flavored water

3. then we cut the bottoms of the bottles off

4. then her dad made a wooden placement holder for the bottles

5. we then set the bottles in the wooden holder

6. after all this was done we ate baby food and took the baby food jars and set them underneath of the bottles so they could catch the creek water we were going to drain into all of the materials

7. we then put the materials (coal bits, pebbles, sand, and rocks) into different orders in each bottle to see which one would clean the water the best.

p.s. we set the bottles upside down and cut holes in the cap so the water could drain. we also put mesh inside the cap so the materials couldn't fall out.
