The Airfire 3.3L Top-Fill Cool Mist Humidifier is an ultrasonic model that adds moisture to rooms up to medium size. It runs quietly at under 28 dB, has a soft night light, and accepts tap, bottled, filtered, or distilled water. It suits bedrooms, nurseries, and desks. Compared with rivals that demand distilled water, it is more flexible, but its 3.3 L tank is smaller than many large-room humidifiers and it lacks smart features.

A few drops of essential oil can be added directly to the water tank to diffuse a scent.
