For what it is worth i have taken to understanding the exact processes that the nasal tract goes through to provide clean allergen free air to the lungs by using an inert cellulose powder as a research tool:
It is a four stage filter.
1. the outer visible nose is where precipitation takes place of the heavier particulates (such as coal dust for example) from the inhahed air because of the slight drop in air pressure due to the nostril opening being relatively small compared to the nostril void.
2.the inner nasal tract is so shaped as to 'squeeze' the transient inhaled air, which combined with a further slight drop in air pressure, causes a range of particle sized material to be impinged onto the mucus lined air ways. Mucus is an amazing material which contains peptides and enzymes to render harmless any deposited germs prior to disposal of the spent mucus via the digestive tract. The mucus is held in place and continually moved on to the back of the throat by the to and fro movement of the cilia hairs.
3 and 4. the tonsils and adenoids, because of their shape and position in the later stage of the nasal tract, attract and entrap any of the very smallest particles that have escaped the main inner filter area.
The reason for the use of the specific cellulose powder is because this unique material turns to a gel like consistency which to all intents and purposes mimics real nasal tract mucus. It has been found over the last 30 years of studying the nasal tract that Allergies (the cause of hay fever et al) only cause trouble when the supply of mucus is missing or of a poor quality, or is overwhelmed by the amount of entrained material in the inhaled air. Mucus is the essential filtration medium.
Many clinical trials have been done worldwide in respect of hay fever effect which normally stops in seconds when a very small amount of the cellulose is puffed into each nostril.
Nasal conchae swirl the air to get inhaled particles to stick to the hairs and mucous membranes in the nasal cavity.
The nose has filtering hairs to catch the initial things and then there is a sticky mucus that catches dust.
No, they move mucus out of the nasal cavities.

Mucus is a substance produced by the lining of the nasal cavity. This mucus helps moisten and filter incoming air.

The nasal cavity filters, humidifies and warms incoming air. It also contains olfactory receptors.
There are tiny hairs called Cilia which line the nasal cavity. These hairs help trap dust particles which are then expelled out the nose.

Mucus Membrane-lining the nasal cavity.
When you inhale, air is drawn into the nasal cavity, which warms, moistens and filters the incoming air. The nasal cavity includes mucus, immunologic tissue in the form of the adenoids to combat allergens, and a pathway to excrete mucus during times of infection/illness. In addition, neuroreceptors for the sense of smell are located in the nasal cavity.
Nasal cavity mucosa... as air passes thru the nasal cavity, it's warmed, moistened, and filtered by the nasal cavity mucosa. The air that flows directly beneath the superior part of the nasal cavity may stimulate the olfactory receptors in the mucosa region.
No, the conchae in the nasal cavity does
The bony nasal cavity is made up of the hard palate and the palatine process of the maxilla. The nasal cavity is made up of the rest of the nasal sinuses and includes the bony nasal cavity.
