Masks are easy-to-use for treatment of upper respiratory tract diseases and irrigation of all nasal and pharynx cavities, as well as larynx and trachea.
Larger quantities of aerosols deposit in the upper airways when masks are used.
Masks are needed for nebulization therapy in children up to 3 years, since it is impossible for such patients to inhale through mouthpieces — children mostly breathe through the nose due to their anatomy.
It is recommended to use masks of appropriate sizes.
Tight-fitting masks reduce loss of spray in young children.
