Reducing dust mite exposure involves several strategies: 1. Environmental Controls: Use dust-proof covers on mattresses and pillows, wash bedding in hot water weekly, and maintain low indoor humidity levels. 2. Cleaning Practices: Regular vacuuming with a HEPA filter vacuum cleaner, dusting with damp cloths, and reducing clutter can help minimize dust accumulation. 3. Air Filtration: Using air purifiers with HEPA filters can also reduce airborne dust mite allergens.
