[Importance of air purifiers in the prevention of respiratory allergy].

Abstract

Prevention of respiratory allergy and thus diminution of its prevalence consists of the application not only of preventative measures on the allergens themselves, but also on atmospheric pollutants such as NO, CO and diesel particles. These modify the allergens and increase synthesis of allergen-specific IgE. Use of air purifiers, on condition that they have HEPA or ULPA filters may contribute to reduction of allergenicity linked to pollutants and are one of the not-negligible means of protection from respiratory allergy and asthma in particular.
