How Does It Work?
The Coolizi draws warm air through a water-saturated evaporative cartridge that cools the air by evaporation. As the water evaporates, it absorbs heat from the passing air, lowering the output air temperature by up to 20°F at the vent under optimal low-humidity conditions. The cooled air is then blown toward the user, creating a refreshing personal cooling effect.
This mechanism depends on ambient humidity and is most effective in dry to moderately dry environments. Unlike compressor-based air conditioners, the Coolizi requires no installation, no exhaust hoses, and no heavy power draw — just fill the cartridge with clean water and enjoy instant personal comfort.

Easy Setup — No Installation
No exhaust hoses, no drilling, no professional installation required. Simply fill the water cartridge, power on via USB, and enjoy instant cooling. Perfect for renters and travelers.
Personal-Zone Comfort

Use & Maintenance
The Coolizi is refreshingly simple to operate. Fill the evaporative cartridge with clean water, and you're ready to go. On moderate settings, each fill provides approximately 6–8 hours of cooling operation. During extended storage, empty the cartridge and allow it to air-dry to prevent musty odors.

- Refill cartridge as needed during use
- Empty and air-dry before extended storage
- No messy water refills beyond the cartridge
Target Climate & Usage
The Coolizi is optimal for dry or moderately dry climates with relative humidity under 50%. It excels in bedrooms, offices, RVs, camper bunkrooms, and small personal spaces — especially in the western U.S. and desert regions.
It provides personal cooling at close range and is not designed for whole-room ambient cooling or high-humidity environments (>60% RH). For dry-climate dwellers seeking installation-free, portable comfort, it's an outstanding fit.
Whisper-Quiet for Undisturbed Sleep
Engineered for near-silent operation, the Coolizi is quiet enough that your spouse won't even notice it's running. It produces a soothing white-noise effect rather than annoying mechanical sounds — making it an excellent companion for light sleepers, nurseries, and shared bedrooms.
