Weighing 212 grams and featuring a battery that lasts up to six hours, it is built to keep users cool throughout the day and night. The fan delivers airflow speeds of up to 25 meters per second, powered by a brushless DC motor spinning at up to 65,000 rpm. It offers five airflow settings, plus a Boost mode for additional power, allowing users to tailor cooling from a gentle breeze to more intense airflow.
Jake Dyson, chief engineer, said, “Since 2009, we’ve been obsessed with airflow. Mastering air projection, reducing turbulence, and refining thermal technology. The HushJet Mini Cool fan is the culmination of that journey: powerful airflow, engineered for life on the move by bringing elite cooling technology from every home to your hand.”
The Number 38
At Dyson, 38 mm is a significant measurement, representing the company’s focus on making products smaller, lighter and higher-performing. It is comparable to the diameter of a watch face and is shared by several Dyson products, including the Supersonic hair dryer, the PencilVac and now the HushJet Mini Cool fan.
HushJet Projection: Powerful and Refined
Dyson’s HushJet projection delivers airflow of up to 25 meters per second, designed to provide rapid cooling in a variety of environments, from offices and commutes to outdoor events and sports venues. The fan can be used handheld, placed on a surface or worn hands-free.
The company says acoustics are as important as performance. With the HushJet nozzle, frequencies have been lowered and high-pitched motor noise reduced, resulting in quieter operation alongside strong airflow.
Dyson color, materials and finish engineer Holly Holmes said, “With HushJet Mini Cool fan, we wanted to create finishes that evoke emotion and context. Bold contrasts for confidence, deep tones for sophistication, and soft hues for calm. It’s about making engineering personal”.

Finishes
The HushJet Mini Cool fan is available in three finishes:
- Ink/Cobalt: A blend of cobalt blue and ink blue designed to reflect both vibrancy and elegance.
- Carnelian/Sky: A matte red tone paired with sky blue for a fresh, cooling aesthetic.
- Stone/Blush: A soft white with a subtle pink tint inspired by mother of pearl, intended to evoke calm and warmth.
Accessories
The fan comes with a neck dock, charging stand, USB-C cable and travel pouch for everyday use. Optional accessories include a universal mount designed to attach to items such as a pram, as well as a grip clip that secures the fan to bags or clothing.
These additions offer users more flexibility in how they carry, position and use the device.
