Asthma is one of the commonest chronic diseases. It is characterised by inflammation and narrowing of the airways in the lungs alongside a “twitchiness” of those airways that leads to symptoms like wheezing and breathlessness. While many new medications have been introduced to treat asthma in recent years, there remains a shortage of non-drug or environmental interventions that can improve asthma with minimal risk of adverse effects. In addition, in recent decades, there has been an increase in the number of people with asthma and other allergic diseases. The precise cause for this increase in asthma is not known but it has coincided with changes to the quality of indoor air with increase in the levels of allergens and pollutants.
The energy efficient houses of today with high indoor temperatures and humidity may, by a number of mechanisms, increase exposure to likely allergens. In addition to allergens, the indoor environment contains other biological materials and pollutants, which can adversely affect asthma control and symptoms. Maintaining high air quality with lower levels of allergens and pollutants could improve the health of individuals with asthma. Therefore, a feasible and practical intervention that can reduce allergen and pollutant levels in the indoor air might reduce asthma symptoms and improve control.
The purpose of this study is to determine the effect of using a Dyson Air Purifier to reduce or remove indoor allergens and pollutants from the home on asthma control and the twitchiness of the airways (bronchial hyper responsiveness) in people with symptomatic asthma.
