FAQ

Who would be the perfect patient to use an Airsonett?
Airsonett is for use in patients with severe allergic asthma who, in spite of taking asthma medication, still has poorly controlled asthma. Airsonett is most suitable for patients with the following clinical profile: Poorly controlled (ACT<18) atopic asthma despite high treatment intensity (GINA 4). Sensitized to at least one perennial allergen.

What are the documented effects on Airsonett?
Airsonett has undergone rigorous clinical trials over a number of years. The largest trial, The 4A Study, included 282 patients in 19 European asthma clinics.

This placebo controlled European clinical trial showed that use of Airsonett results in significantly improved quality of life, airway inflammation and systemic allergy6 compared to placebo. The trial demonstrates that patients with inadequately controlled perennial allergic asthma, despite regular pharmaceutical treatment, can achieve significant symptom improvements from Airsonett treatment.

How does the Airsonett work?
Airsonett is based on the Temperature controlled Laminar Airflow (TLA) technology. The air from the room enters the Airsonett and passes a filter that captures allergens and other particles. The filtered air is cooled to slightly below the ambient room temperature and is supplied with a low velocity from the airshower. The slightly cooled air creates a zone of “allergen-free air in the breathing zone.

What is the difference between Airsonett and a conventional air purifier?
Conventional air purifiers have not demonstrated clinical effect on asthmatics (Kilborne et al). The drastic reduction in night-time allergen exposure created by Airsonett is the main reason for Airsonett’s success in an area where so many other other domestic allergen avoidance measures have failed.

What types of particles does the filter get rid of?
Studies show that Airsonett reduces particles (both ≥0.5μm and <0.1μm) in the breathing zone by more than 1,000 times compared with no intervention.

How can it have an effect during daytime when it is only used during night time?
Nocturnal exposures have a significant impact on inflammation and symptoms in asthma This may be a consequence of circadian changes in autonomic function, steroid hormones and immune responsiveness. Studies have shown that daytime symptoms and activities are significantly improved from nocturnal Airsonett.

Can Airsonett have an effect on eczema and in that case how can that be when the clean air only reach the breathing zone / face?Other allergy induced diseases than asthma, such as rhinitis and eczema, can also be triggered by airborne allergens and other particles (irritants). Minimizing airborne irritants from the breathing zone may therefore alleviate symptoms of these diseases.

For how long should a patient be treated?
Airsonett should be used continuously every night.

Who is responsible for insurance if any unpredicted electrical malfunction of Airsonett would occur?
Airsonett has full product liability insurance for the device. We manufacture to the highest EU regulations ISO 60601-1. Airsonett has been tested and found to be in conformity with regulation IEC/EN 60601-1 for Medical electrical equipment.
