It will never get deep into your lung. Only particles on the micrometer range can get into lung. For carpet fiber, it will be blocked by hairs in your nostrils. Ahhhhhhh-Chiiiii
how about little babies who do have (a lot) nostril-hairs? thanks

haha, your nostril hair is just first defense. Our nasal airway is highly tortuous, and most large particles will hit mucosa wall and come out with mucus. Wonder why we have things to pick from nose :) Our deep airway is coated with cilia - a layer of micro-hairs that sweeps in a concerted manner to move particles out of lung. Our nervous system is wired in a way that irritation to airway leads to sneeze and cough, mechanically blowing things out at speed over 10m/s. As a result, only particles
