I was only able to come up with one way for now. See explanation below.
Here is one way that we may use filtration in daily life:
1) Drinking water: The water we drink is filtered water, which is often more pure and safe than regular freshwater that may be found in rivers and lakes. We filter our water because it reduces many risks and health concerns that may be associated with drinking unfiltered water, which often contain bacteria and parasites.
I hope that helps!
