USB Air Humidifier with Projection Night Lights – 40ml/h Mist, 200ml Tank, Safe for All Ages

This USB air humidifier uses polymer mist technology to diffuse moisture into the air without leaving water droplets on surfaces. Operating below 30 decibels with zero radiation, it is safe for use around elderly people and children. The spray volume reaches 40ml per hour, quickly meeting relative humidity needs in rooms up to medium size. Its USB power compatibility means it works wherever a USB port is available – at home, in the car, or in a dormitory. Available in pink, dark blue, light blue, and white, this humidifier is a practical solution for dry-air discomfort in a variety of everyday settings.

Features and Construction

Built from ABS, PP, PE, silicone, and electronic components, this humidifier is lightweight yet sturdy. Its compact design integrates a built-in night light projection function for ambient use during low-light conditions. The unit is powered by a standard DC5V USB connection and draws between 200mA and 450mA at 3.5W.

Material and Build

The main body is made from ABS and PP plastics with a PE and silicone base, chosen for their resistance to moisture and ease of cleaning. Electronic components are fully enclosed to protect against accidental spills. The cotton swab measures 7.75mm x 134mm and is replaceable when mist output reduces.

Size and Practical Fit

With a water tank capacity of 200ml, the unit is compact enough to sit on a desk, bedside table, or car cup holder. It weighs very little and requires no permanent installation – simply fill, plug into a USB source, and switch on. The 5-hour runtime from a single fill covers a full workday or a night's sleep.

Uses and Placement

This humidifier is designed for environments where dry air causes discomfort: bedrooms during winter heating, car cabins on long journeys, office desks with air conditioning, and baby rooms where quiet operation is essential. Its zero-radiation output makes it suitable for continuous use near people.

Event or Professional Use

In hotel rooms or small meeting rooms, the quiet mist adds moisture without distracting background noise. The night light function can serve as a subtle ambient light for presentations or relaxation. USB power ensures it works with most laptops, power banks, and car adapters.

Everyday Home Use

At home, position the humidifier in living rooms, bedrooms, or nurseries on a flat surface. The polymer mist prevents water rings on furniture. A single fill lasts a full evening, reducing the need for constant refills. The device can be switched off easily when not needed.

Benefits and Buying Value

This humidifier addresses dry air problems without the risk of wet surfaces or high electricity consumption. Its polymer mist technology sets it apart from evaporative or steam humidifiers that can leave floors wet or use more power. With a low wattage of 3.5W, running costs are minimal.

Reuse and Low Maintenance

The cotton swab is designed for simple replacement when it becomes clogged or inefficient – just remove the old one and insert a new standard 7.75mm x 134mm swab. The tank can be rinsed with clean water. No special cleaning chemicals or filter replacements are needed beyond the swab.

Why Choose This Product

If you need a quiet, portable humidifier that works in cars, offices, and homes without surface wetting, this model offers a practical solution. Its 200ml tank and 40ml/h output give consistent humidity for up to 5 hours. The colour options (pink, dark blue, light blue, white) allow matching to your décor.
