  • It’s all about people and the right to live a life where the symptoms of allergic diseases, such as asthma and eczema, are obsolete. We wake up every morning to make innovations towards this difference.


The clinical and economic evidence demonstrates that Airsonett is clinically effective and cost-effective compared to standard care.

The Airsonett is very helpful as it enables my son to sleep at night. Last year he had 26 visits to hospital and a lot of GP visits. So far this year he has had about 5-6 GP visits and maybe one or two hospital visits only. He wakes up about 50% less now at night and family life is a lot less stressful!
