The project ”Allergen-free Indoor Environments through Innovative Ventilation Strategies” was initiated by Karolinska Institutet and intended to test how airborne allergens from furred animals can be minimized in indoor environments.

The aim of the project was to design smart systems for measurement, control, and ventilation/air purification with the objective of reducing the amount of allergens indoors. The vision was to develop ventilation solutions that can be applied in residential and community planning to minimize the problems for people with fur allergy. Previous results from an experimental environment were applied in KTH Live-In Lab, where pets were introduced into the testbed.

Last month the scientific article on airborne allergen particles was made public through the Wiley Online Library , one of the largest and most authoritative collections of online journals, books, and research resources, covering life, health, social, and physical sciences.

The article was officially published in the Clinical & Experimental Allergy journal , which is the Official Journal of the British Society for Allergy & Clinical Immunology.

Article abstract

Exposure to dog allergens is almost impossible to avoid, as dogs are part of our society and frequently encountered both outdoors and indoors. This poses problems to individuals allergic to dogs, a common condition with reported sensitization rates around 20%. It is therefore crucial to increase our understanding on how dog allergens spread in the environment and on exposure by inhalation.
