Clinically proven

Health economics studies confirm lower treatment costs compared to pharmacological treatment options, fewer clinic visits and better control over patient symptoms.

This is how it works

Airsonett Air4 creates a zone of 99.5% clean air, free of particles and allergens around the face during night sleep. The airways and immune system rest and can withstand allergens even during the day.
