A Look at Indoor Allergen Environmental Control

Abstract

Environmental control is important in the management of allergy, particularly indoor environmental control. These measures may be helpful not only in allergic rhinitis, but also asthma. House dust mite allergen is a major indoor allergen and measures to control allergen level include impermeable encasings for the bedding (perhaps the most important measure), washing bedding preferably at high temperature (130°F), decreasing relative humidity in the home, not having carpet, or if so, using an effective vacuum system, and using air filter devices. The use of chemicals called acaricides have been marketed to kill dust mite as well. Animal dander, another clinically important indoor allergen is best managed by removal of the pet from the home. However, using encasings in the bedroom, vacuuming with an effective vacuum system, using an air filter in the home, and possibly washing the cat, are modalities used to decrease animal dander. The majority of patients tend to benefit most from avoidance of allergens (p...
