Most bedrooms feel best in a moderate humidity range. Running too high can increase condensation risk near windows and cool exterior walls, so periodic monitoring is useful.
FAQs
Ultrasonic vs evaporative for bedrooms?
Ultrasonic models are often quieter and compact; evaporative models are typically self-limiting but may use replaceable wicks.
How often should I clean the humidifier?
Light weekly cleaning and regular full rinses help reduce mineral buildup and odor.
Where should a humidifier be placed?
On a stable elevated surface with airflow clearance, not directly against walls or electronics.
