This mini ultrasonic humidifier uses polymer mist technology to diffuse moisture into the air without leaving wet droplets on the surface underneath it, and it doubles as a projection night light. It runs on any USB power source, which makes it usable at a desk, in a car, or beside a bed, and it operates below 30dB, quiet enough for use around infants and light sleepers.
Key Features & Benefits
- Polymer mist diffusion technology — moisture disperses directly into the air instead of condensing into water droplets, so it won't leave a wet ring on a desk, nightstand, or car console.
- Below 30dB noise level — quiet enough to run in a nursery, bedroom, or shared office space without becoming a distraction; the sheet also notes zero radiation and no irritant output, making it suitable for use around children and older adults.
- 40ml/h mist output (per manufacturer spec table) — designed to raise relative humidity in a room noticeably faster than lower-output personal humidifiers. (See gap note above regarding a conflicting 35ml/h figure elsewhere in the source material.)
- 200ml water tank with roughly 5 hours of use time — enough for an extended work session, a nap, or an overnight car ride on a single fill.
- USB-powered, portable design — runs off any USB power source (wall adapter, power bank, laptop, car USB port), so it isn't limited to a fixed outlet.
- Projection night light function — adds a lighting effect to the humidifier housing, letting it double as ambient lighting for a bedroom or nursery rather than a purely functional device.

Why Buyers Choose This
Most compact humidifiers in this category do one thing: add moisture to the air. This one adds a projection light effect on top of that, runs quiet enough (under 30dB) for a baby's room, and uses polymer diffusion instead of a basic mist stream, so it doesn't leave condensation pooling on the surface underneath it. Running entirely on USB power also means it isn't tied to one room; the same unit works at a desk, in a car, or on a nightstand.
FAQ
Will this leave water droplets or a wet ring on my desk or nightstand?
No. It uses polymer mist diffusion technology designed to disperse moisture into the air rather than condensing back into droplets on the surface below the unit.
Is it quiet enough to use in a baby's room?
Yes. It runs below 30dB and is described as producing zero radiation and no irritating output, positioning it as suitable for use around infants, children, and older adults.
How long does it run on a full tank of water?
The 200ml tank provides approximately 5 hours of use time per fill, based on the manufacturer's rated output.
Can I use this in my car?
Yes. It runs on standard USB power, which includes car USB ports, and the product is explicitly listed as suitable for car use alongside bedrooms, living rooms, offices, and dorms.
Care Note
Empty and rinse the water tank after each use to prevent residue or mineral buildup on the mist diffusion element. Use the included cotton swab to clean the mist outlet as needed. Wipe the housing with a dry cloth only, and avoid submerging the base or any electronic components in water.
