The Honeywell HEV320B is a simple evaporative humidifier designed for small to medium-sized rooms, covering approximately 300 to 500 square feet. It features a cool mist type and offers a runtime of up to 23 hours, but it does not include a humidistat. Positioned below models like the Honeywell HUL430B and HUL545W in Honeywell’s lineup, it lacks many of their advanced features. The bottom-filling tank has a usable capacity of 3.5 liters (0.9 gallons), providing nearly a full day of continuous operation.
This humidifier is suitable for general home use, though its humidification capacity is on the lower end, which may require purchasing a second unit for larger spaces. It does not have a built-in humidistat or auto-off function, meaning it won’t shut off automatically when the desired humidity level is reached. However, it is impressively easy to clean, has low power draw, and offers a long runtime, reducing the need for frequent refills. Pros – Impressively easy to clean. – Low power draw. Cons – Humidification capacity is on the lower end. – No humidistat or auto-off features.
