Mold is the enemy. We tested humidifiers to find the easiest to clean and the most effective for congestion relief.
The best humidifier is the one you will clean. Ultrasonic humidifiers are quiet but can spread mineral dust if you don't use distilled water. Evaporative ones are self-regulating but have filters to replace. We prefer designs that go fully in the dishwasher.
