Air that is breathed in goes past moist tissues and moist hairs. The dust and other foreign particles stick to the moist tissues and moist hairs. Breathing through the mouth filters out fewer foreign particles, so is less good for the lungs.
Tiny hairs in the nose called cilia and mucus trap the dust and other particles and either push them back out the nostril or down into the digestive system.
Mucus and something else
mucous covered membranes and microscopic hairs called cilia sweep dust away, then sneezing and coughing will expel it from the body or it will be swallowed
Weirdly enough, your nostril hairs stop dust from traveling into your lungs.
It dose reach the lungs but a sneeze or a cough brings it right up
By the goblet cells and cilia in your windpipe. Smoking kills these cells, which is when smokers get ill.

Mucus is the secretion produced by the respiratory system that traps dust and other inhaled foreign particles. It helps to protect the lungs by capturing these particles before they can reach deeper into the respiratory tract.
To assist in removing dust particles and other unwanted foreign bodies that have entered the air passages.

Dust cells are specialized cells found in the respiratory system that help remove foreign particles, such as dust or pathogens, from the airways. They play a role in defending the lungs against inhaled pollutants and maintaining respiratory health. Dust cells are also known as alveolar macrophages.
Cilia are tiny hairs that line the respiratory tract and help trap dust and foreign particles to prevent them from entering the lungs. These hair-like structures wave in a coordinated manner to move mucus and trapped particles out of the respiratory system.
Our lungs are quite sensitive. The blood vessels in the nose warm the air to a temperature close to our own. The moisture is simply secretions designed to trap foreign particles such as pollen and dust - to sopt them reaching the lungs.
Mucus in the nose and trachea traps foreign particles and bacteria. The cilia, tiny hair-like structures in the respiratory tract, move the mucus and trapped particles upwards to be swallowed or expelled. This process helps to protect the lungs and respiratory system from harmful invaders.
The hairs in the nose are there to stop dust particles being inhaled into the lungs. Dust combined with natural mucus - is what 'bogies' are formed from (sorry if you're eating !)
A dusty enviroment can affect our lungs when we breathe it in because the dust particles can get trapped in our lungs which would affect our breathings the particles travel through the the air and we inhale it!
