ELI5: Explain Like I'm 5

Nose filter

Do you know what a nose is? It's that funny-looking thing on our face that helps us breathe. When we breathe in air, it goes through our nose and into our lungs so we can get oxygen.

But sometimes, the air we breathe in can have things in it that we don't want in our body. Things like dust, pollen, or even tiny germs that can make us sick.

That's where a nose filter comes in! It's like a little screen that sits inside our nose and catches all those things before they can get into our body.

Imagine it like playing catch with a ball. When you toss the ball to someone, they have to catch it with their hands, right? Well, the nose filter is like someone catching the bad stuff in the air before it can get into your body.

It's a simple and easy way to keep our bodies healthy and happy!
