Clinical Effects of Temperature Controlled Laminar Airflow (TLA)

The intervention is designed to reduce the allergen load in the patients breathing zone by vertically displacing the allergens, originating from the bed and the ambient room environment, with a temperature controlled laminar airflow (TLA) during night sleep. The airflow is filtered through a high efficiency particulate air filter(HEPA), slightly cooled and ''showered'' over the subject. Due to the higher density, the cooled air descends slowly, and displaces the allergens from the breathing zone.
