Effective treatment of
allergic asthma and eczema
– without side effects

Airsonett® Air4 is a medical device for effective home treatment of allergic asthma and eczema. The patented TLA technology provides 99.5% clean air in the breathing zone. Your airways and immune system can rest and recuperate when you sleep, and you wake up rested, ready for a new day.

Treatment with TLA is recommended by the Swedish National Board of Health and Welfare (Socialstyrelsen) and the Swedish paediatricians ‘allergy association (BLFA). It has also been reviewed in the UK by The National Institute for Health and Care Excellence (NICE) and proven cost effective by Health Improvement Scotland.
