They don't the only way to keep dirt from going into your throat is to breathe through your nose where your nose hair and mucus provide traps for dirt.
Yout throat cells have tiny hairs which trap and prevent dust and dirt from going into your body, you also have these cells in your nose too.
Mucous and celia propel dust
They do not stop it but the mucus and motion of the cillia remove said microbes and dust should they get into the lungs.
The cilia on their surface trap dust and microbes, then pass the trapped substances along with mucus to the throat, where they can then be swallowed. This then protects the lungs.
Epithelial cells I think.... or Cilia, no i think Cilia are hairs!
To prevent dust particles and harmful materials from entering the lungs .

Epithelium Cells are usually flat and cover the surface of organs. There is a special type of epithelial cell. Millions of epithelical cells line our windpipe and help stop dust travelling all the way into our lungs. Once the dust has been stopped, they also push it back up the windpipe to the throat.
cillliated epillithial cells or cillia for short, they clean dust and mucus from our lungs
When you inhale, the air you breathe in is cleaned by cilia in your trachea. This helps remove dust and other pathogens from the air when it is on its way to your lungs
Your skin and your mucus membranes are your body's first line of defense against any pathogen whether that be dust, or a virus!
Main function is to keep things from entering the lungs from the nasal cavities. They actually block a lot of particles, dust, allergens etc.
Cilia
Ciliated Epithelial Cells have tiny hairs on them. These hairs sweep away any unwanted things, such as bacteria and dust which is trapped in mucus.
