# DREO HM524 6L Ultrasonic Humidifier

The DREO HM524 is a 6-liter ultrasonic humidifier with top-fill access, adjustable humidity control, an aroma diffuser, and a night light. The listing claims up to 60 hours of operation in sleep mode, so that runtime is mode-specific rather than a general maximum for every setting.

## Before you buy

- The listing gives the electrical specification as “26 watt-hours,” a unit of energy rather than power. Treat that entry as a source-listed value, not a confirmed power rating. The 60-hour claim is specifically for sleep mode. Coverage, output, sensor accuracy and noise figures are listing claims, not independently verified measurements.

## Customer feedback

Customer feedback highlights perceived effectiveness, quiet operation and easy cleaning, with some customers appreciating the large tank and all-day use. Reports about mist output and reliability are mixed, including accounts of units stopping misting or ceasing to work.

These are customer perceptions, not proof of a specific cause or failure rate.

- Positive themes: Customers appreciate the large tank, easy cleaning and moisture without the room feeling damp.
- Mixed feedback: Feedback on mist output is mixed, with reports of both good output and units that stop producing mist.
