These are called cilia.

Nose hairs act as a filter, trapping dust, pollen, and other particles from entering the respiratory system. This helps prevent harmful substances from reaching the lungs and causing irritation or infection, ultimately supporting overall respiratory health.
Serve as a filter for screening out harmful substances.
No, the stomach does. The liver prevents harmful substances from goig to your blodstream.
it is carried to the liver to filter harmful substances,
The liver filters harmful substances from the blood and metabolizes them into less toxic compounds. The kidneys then filter these compounds out of the blood and excrete them in the urine. Additional detoxification processes can occur in the lungs, skin, and intestines before harmful substances are eliminated from the body.
The nose cilia are tiny hair-like structures in the nasal passages that help filter out particles like dust and bacteria from the air we breathe. They trap these particles and move them towards the throat where they can be swallowed or expelled. This helps to keep the respiratory system healthy by preventing harmful particles from entering the lungs and causing infections or irritation.
Filter Paper
The respiratory tract filters air throughout its length. From the entry to the nose (nose hairs), through the sinuses, the bronchi and bronchioles, down to the entry to the alveoli, different sized particles are filtered out all along the way. The larger particles are removed in the nose the sinuses. The smaller ones are filtered in the bronchioles, where they get stuck to the moist walls. The smallest particles, generally less than 10 microns in aerodynamic diameter, get past all the filtering mechanisms and reach the alveoli.
Bacteria and dead cells are removed from lymph within lymph nodes, which are small bean-shaped structures located along the lymphatic vessels. Lymph nodes contain immune cells that help filter and eliminate these harmful substances from the lymph fluid before it is returned to the blood circulation.
