The Nasaljet 3A Fast Nasal Douche is described as a micronized nasal douche; the description also includes the wording “Anteawash Micronized Nasal Douche.” It delivers hydromineral solutions locally with the aim of sanitizing the nasal cavity and acting in cases of infection or other conditions. The description indicates its use to clear mucus from the nasal cavities of very young children who do not yet know how to blow their nose, or cannot do so vigorously and consistently, and of people who, due to physical impairments, cannot do so independently.

The source also attributes to the nasal douche a preventive function against bacterial attacks and seasonal illnesses, as well as indicating it for respiratory disorders in children, including very young children. It also mentions rinsing with thermal water to sanitize the nasal passages, associating this with an anti-inflammatory action.
