Important results from the project

Well performed studies on spread of allergens from pets are lacking and consequently evidence-based advice on how to limit the spread is lacking. In this feasibility study, we have evaluated air sampling methods and developed analyses of allergens in air samples. After the end of the project, we will add some further analyzes and compile a method’s report. In future studies our data can be used to suggest suitable methods when studying allergen spread and exposure. A full-scale study of health effects in a residential environment is not considered feasible at present.

Expected long term effects

In this feasibility study, we have found that reliable data on spreading of pet allergens are best generated under well-defined experimental conditions. Our study on the collection method and detection of allergens can offer tools for such controlled studies, where different measures for ventilation and air purification can be evaluated. For example, activity may be controlled by activity meters on animals / humans. Data on pet allergens in air samples can be used to create computational fluid dynamics models to minimize allergen levels in indoor environments.

Approach and implementation

We have carried out a pilot study on how collection and detection of airborne allergen can be performed. We have also discussed the project with experts from various disciplines including building technology, immunology / allergy, environmental medicine and aerosol technology. The original plan was very ambitious. Our conclusion from the feasibility study is that basic data on the spread of pet allergens in air must first be established under controlled conditions, to be verified at a later stage by testing at more "real" conditions.
