Dust allergies are often caused by dust mites, microscopic creatures that thrive in warm, humid environments. To reduce dust allergy symptoms, focus on minimizing dust mite exposure:
- Use a high-efficiency particulate air (HEPA) filter (HEPA) to help remove dust allergens from the air. Clean the air filters regularly.
- Vacuum rugs, carpets, upholstered furniture and other surfaces regularly: It's a good idea to vacuum at least twice a week.
- Cover mattresses and pillows in zippered dust-proof covers.
- Wash sheets and blankets weekly in hot water (at least 120 degrees F).
- Reduce clutter, stuffed animals, and other places where dust mites live.
- Use air conditioning or dehumidifiers to reduce the humidity to between 30 and 50 percent.
- Damp dust the room at least once a week.
If your efforts to reduce exposure to indoor dust don't provide adequate relief, your allergist may recommend a prescription or over-the-counter medication. These medications can help relieve symptoms like itching, sneezing, and runny nose.
