The Nostrils or the Nose.
That would be the nose. It warms, filters, and humidifies room air. Its our built in heat and moisture reclaimer.
The pharynx is part of two systems, the digestive and the respiratory. It moistens, filters and warms the air taken into the lungs.

During respiration it is the nose or nasal cavity that filters the air using mucous and hair within the nose, warms the air and moistens. This is performed when inhaling.
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.
The nasal cavity warms and moistens air as it enters the body.
The nasal cavity filters, humidifies and warms incoming air. It also contains olfactory receptors.
Most breathing in healthy humans occurs through the nose. As air enters the nasal cavity, it is filtered of large debris by hairs lining the inside of the nose, and then further filtered through the nasal conchae, an area of folded, moist tissues; this also warms the air to near body temperature when it is cold.
Nasal cavities act as a both a filter and a humidifier, filtering out much of the contaminants in the air that you breathe, and humidifying the air prior to the airs entrance into the lower respiratory tract (trachea, lungs).
The cabin filter on a 2002 F550 is located behind the glove compartment. It is easily accessible in the area and filters incoming air.
