- • Cooling Performance: Three modes and three wind speeds combine with a honeycomb waterfall evaporative system, claimed to lower surrounding temperature by 4-6°C.
- • Best for: Personal cooling at desks, bedrooms, small offices and outdoor seating where a compact, portable unit is needed.
- • Not ideal for: Cooling large rooms or replacing a whole-house air conditioning system.
USB-powered operation and a sealed 700ml top-fill tank deliver up to six hours of humidified cooling per fill. Low-noise performance and an RGB night light make it suitable for bedside and desk use.
Personalised Cooling Control – with 3 modes and 3 wind speeds
Three selectable modes are Natural Wind, Low Cool Mist and High Cool Mist, each available across Low, Mid and High fan speeds, with up/down adjustable airflow direction. The control layout lets users change mode and speed without moving the unit.
Fine-tune airflow for a desk, bedside table or outdoor bench, and add ice cubes when a stronger cool mist is wanted.
Extended Runtime and Easy Refills – thanks to a 700ml top-fill sealed water tank
A sealed 700ml tank supplies up to six hours of operation when filled, and a transparent water-level window shows remaining water. An auto-protection function switches to natural wind once the tank is empty to prevent dry operation.
Overnight naps or a work session at a desk are possible without constant topping up, and top-fill access keeps refills quick and spill-free.
Gentle Humidifying Cool Breeze – with honeycomb waterfall evaporative system
Honeycomb waterfall evaporation and two mist humidification holes atomise ice water into a moist airflow, which the manufacturer states can lower surrounding temperature by 4-6°C. The evaporative method avoids the overly dry air typical of refrigerated cooling.
Breathable, moisturising airflow helps reduce skin and throat dryness while cooling, making it suitable for dry, hot climates.
