✓ Target 35–50% relative humidity in winter — below 30% causes dry skin and static; above 55% encourages mold
✓ Use distilled water in ultrasonic humidifiers to eliminate the white mineral dust that settles on furniture
✓ Clean the tank every 3 days during heavy use to prevent mold and bacteria buildup
✓ Place humidifiers on a waterproof mat away from electronics, books, and wood furniture
