Solution
There are tiny, fine hair-like outgrowths called cilia inside the nose from where the air passes inside. Larger dust particles get caught in these hairs. The air going inside the trachea thus gets filtered. There is also a layer of a sticky substance called mucous. The dust and smoke particles stick to the mucous. Thus, the air that we inhale gets purified before it reaches the lungs.
