Our take on the Honeywell Compact Ultrasonic Mini Cool Mist Humidifier

The Honeywell HUL525B is a compact ultrasonic cool mist humidifier with a 0.5-gallon tank, built for desktops, nightstands and small rooms. It runs up to 24 hours per fill, has variable output, a directional mist outlet and auto shut-off, and needs no filter. It is quieter and simpler than larger warm-mist or evaporative units, but its small tank and plastic build suit a single personal space rather than a whole room.

What reviewers say

Owners of compact Honeywell ultrasonic humidifiers generally describe them as quiet and easy to fill, and useful for a bedside or small office. Common complaints center on the small tank, mist output fading as the water level drops, and mineral dust on furniture.

Questions and answers

Does it need a filter?
No. It is a filter-free ultrasonic unit, so there are no replacement filters to buy. Regular cleaning of the tank and base is still needed.
How long does one fill last?
Up to 24 hours on low output. On higher settings the 0.5-gallon tank empties much sooner, often within a night.
Is it good for a bedroom?
Yes, for a single bedroom or bedside. It is quiet and compact, but too small to humidify a large open room.
Can I use tap water?
Yes, but hard tap water can leave white mineral dust on furniture. Distilled water reduces that.
Does it shut off automatically?
Yes. It shuts off when the water runs out, so it can run overnight unattended.
How does it compare with a warm mist humidifier?
It adds no heat and uses less power, and there is no risk of hot water. Warm mist units can feel more comfortable in cold rooms and produce less white dust.
Where is the Honeywell Compact Ultrasonic Mini Cool Mist Humidifier cheapest?
