Although these recommendations focus on the home environment, reductions in exposures to allergens and irritants are also appropriate in other environments where the patient spends extended periods of time, such as school, work, or day care. Keep the patient's bedroom door closed. Consider placing dense filtering material over forced air outlets to trap airborne dander particles. Remove upholstered furniture and carpets from the home or isolate the pet from them to the extent possible. House-Dust Mite Allergen.
Mites depend on atmospheric moisture and human dander for survival.
High levels of mites can be found in dust from mattresses, pillows, carpets, upholstered furniture, bed covers, clothes, and soft toys. The patient's bed is the most important source of dust mites to control. Encase the pillow in an allergen-impermeable cover or wash it weekly. Wash the sheets and blankets on the patient's bed weekly in hot water. Remove carpets from the bedroom.
