Levoit Dual150 Cool Mist Humidifier 3L — Quiet Bedroom Unit with Aromatherapy and 25-Hour Run Time

Designed for bedrooms and small-to-medium living spaces, the Dual150 combines a sizable top-fill water tank, a 360° nozzle, and a simple control knob to deliver steady humidity without disruptive noise. ETL-certified and made from BPA-free materials, it supports aromatherapy and includes a cleaning brush and replaceable filters to keep mist output efficient and cleaner over time.

How long will the humidifier run on a single fill?

On low output, the 3-liter reservoir can provide up to about 25 hours of continuous mist—enough to cover approximately three nights between refills. Run time varies with mist level, room temperature, and local humidity.

• Tank capacity: 3.0 liters
• Maximum continuous runtime: up to 25 hours
• Coverage: roughly 107–290 ft² (10–27 m²)
• Power draw: 25W for energy-efficient operation

Is it quiet enough for nighttime use and baby rooms?

Yes—the Dual150 operates at or below 28 dB in normal conditions, keeping background noise minimal for sleep and infant care. It’s engineered to produce a steady mist without ticking or high-pitched sounds.

• Rated noise level: ≤ 28 dB
• Auto shut-off when water is depleted for safe overnight use
• BPA-free construction suitable for family settings
• Includes a cleaning brush to limit mineral buildup and noise changes over time

How do I add fragrance or maintain the unit?

The base contains a dedicated aromatherapy chamber; add 10–15 drops of essential oil to enjoy light scenting while the unit humidifies. Routine care includes using purified or distilled water, replacing the water filter monthly if your supply is hard, and cleaning the tank before first use and regularly thereafter.

• Aromatherapy: 10–15 drops of essential oil in the base chamber
• Recommended water: purified or distilled to avoid white dust
• Filter lifespan: approximately 1 month, depending on water hardness
• Maintenance: top-fill design and included brush simplify cleaning

What safety and control features does the Levoit Dual150 have?

The Dual150 offers simple, tactile controls—a single knob to adjust mist output and a rotating nozzle for precise mist direction. Safety features include ETL certification and an automatic shut-off when the tank empties, helping prevent dry operation.

• Control: single knob for mist intensity
• Nozzle: 360° rotating spout for targeted misting
• Certifications: ETL certified for electrical safety
• Auto shut-off protects the unit when water runs out
