Answer 1

Your nose is basically an air purifier.

You have lots of little hairs that help absorb particles and block other things. Also, in the process of breathing your nose and traveling through your meat tubage, the air gets warmed up and humidified. This is easier for your lungs to process than straight colder/ dry air is.

Bonus fun fact for CPAP users (breathing machines for sleep apnea) they have water humidifiers for this very reason. Without it the dry air being forced into your nose can cause all sorts of irritation, it needs the warmer air to be more accessible and useable to your body (still not always a perfect system though).
