What effect does low humidity have on the airway?
A critical mechanism of action is Airway Hydration. Heated humidification enables the comfortable delivery of high flows and improves mucociliary clearance, which is an integral part of our upper airway defense system.

The rapidly-beating cilia grind to a halt within 15 minutes, such is the vulnerability of this environment.
