Perfect for my home office

Placed it on my desk pointed at me. The mist function makes the afternoon heat manageable compared to a regular fan.

Frequently Asked Questions

CoolJet uses evaporative cooling with ultrasonic nano spray. It pulls warm air through a water-moistened filter, creating a fine mist that cools the air as it evaporates. A fan then circulates the cooled air around you.

No, CoolJet is designed for personal spot cooling—it works best when placed near you, directly pointing at your personal space. It is not a replacement for a whole-room air conditioner.

Yes. Simply refill the water reservoir when needed, and occasionally empty it and let it dry to prevent odor or buildup. The filter is easy to clean and requires no special tools.

Evaporative cooling is most effective in dry or moderately humid environments. In very humid conditions, the misting effect may be less noticeable, but the fan still provides a pleasant breeze.
