💊 Directions for use, dosage and recommendations for use

Use CoolJet as a personal cooling device to create a comfortable microclimate in one room or space.
It’s designed for quick setup and simple operation, with no installation required—just fill, plug in, and switch on.

For optimal performance, follow these practical steps.
Fill the tank with clean water or add ice cubes for a cooler airflow; avoid adding oils or other liquids that could clog the system.

Plug the device into a USB-C power source and switch it on.
Choose among the three breeze levels to suit your comfort, from a gentle draft to a stronger cooling gust.

• Fill the tank with water or ice, then power on via USB-C; two simple actions to start cooling.
  Allow up to 90 seconds for the initial noticeable airflow.
• Adjust the speed to your preference and position the unit so the airflow reaches your immediate space; avoid placing it behind objects that could block the breeze.
  Keep the unit on a stable, heat-resistant surface.
• Do not exceed the recommended water level or temperature range; if you notice any leakage or unusual sounds, switch off and inspect for obstruction.
  For longer sessions, top up the tank as needed to maintain consistent cooling.

Important precautions include: CoolJet is intended for personal cooling and should not be used as a medical device.
Consult a healthcare professional if you have respiratory conditions or questions about using humidified air in sensitive environments.
