YOUR INVESTIGATION
Build your filter
Choose layers to catch visible bits. Tap a layer again to remove it.
THE BIG IDEA
What is happening?
Filter layers can trap some visible particles. Different materials trap particles of different sizes. A clearer appearance does not mean water is safe to drink.
Simplified model: A visual model only. Filtering does not necessarily remove germs or dissolved chemicals; never drink the filtered water.
