Air filters to prevent air pollution
I've been looking forward to stick out in the science fair. I'd like to do something that would help the world. So I thought about helping to stop air pollution by using a huge air purifier, but that's been covered by someone from the Netherlands and uses too much components. So I thought to myself, what if we could stop pollution before even exiting factories and cars before they could reach our lungs. And the invention will have way less components. That's when I though about a multi-step air filter to place in our house chimneys, factory chimneys, and car excuse pipes.
