How the Cooling Ace Works

Simple evaporative cooling technology for personal comfort

1. Fill with Water

Fill the evaporative cartridge with clean tap water. For an extra cooling boost, add a few ice cubes. Refill approximately every 6–8 hours on moderate settings.

2. Warm Air Drawn In

The device pulls warm room air through the water-saturated cartridge. As water evaporates, it absorbs heat from the air, naturally reducing the output temperature.

3. Cool Air Delivered

Enjoy cooled airflow directed right at you — up to 20°F cooler under dry conditions. Creates a personal cooling zone without wasting energy on empty rooms.

Best mini cooler I've tried

Strong, easy to use, and definitely lowers the temperature in the room. It has a white-noise kind of sound even at the highest settings so it's more soothing than anything else. No annoying noises. The best mini cooler I've tried. Would highly recommend it!

Great for shared office use

I tend to run hot and my coworkers that share an office with me are always cold, so this helps me stay cool at work. It is quiet so noise is not disruptive and because of the design, it doesn't blow air into my phone so that I sound like I am in a wind tunnel.

Perfect for shared thermostat issues

I live with my elderly grandma who is freezing at anything lower than 78 degrees which leaves me disgustingly hot. So I bought this thing and it works perfectly! A lifesaver! It gets me to a much more comfortable temp during the day. I can take it in different rooms. I love Cooling Ace!

Frequently Asked Questions

Everything you need to know about the Cooling Ace

The Cooling Ace uses evaporative cooling technology. It draws warm room air through a water-saturated cartridge. As the water evaporates, it absorbs heat from the air, reducing the output air temperature by up to 20°F under optimal low-humidity conditions (below 50% relative humidity). The cooled air is then directed toward you for personal zone cooling.

On moderate settings, the evaporative cartridge needs refilling approximately every 6–8 hours. Using clean tap water is recommended. Adding ice cubes can temporarily enhance the cooling effect. During extended periods of non-use, the cartridge should be emptied and air-dried to prevent musty odors.

No — the Cooling Ace is designed for personal-zone cooling, not whole-room ambient temperature reduction. It delivers direct cooled airflow to the user, creating a personal comfort zone. This targeted approach is what makes it so energy-efficient compared to traditional air conditioners that cool entire rooms.

The Cooling Ace performs best in dry or moderately dry climates with relative humidity below 50–55%. In higher humidity conditions, the evaporative cooling effect is diminished because the air already holds more moisture, slowing evaporation. It's ideal for arid and semi-arid regions, or air-conditioned indoor spaces where humidity is already controlled.

Absolutely! The whisper-quiet operation makes it perfect for bedrooms. Even at the highest setting, the sound is more like soothing white noise than a disruptive hum. Many customers report that their partner doesn't even notice it's running in the same room.

Coolizi offers a 30-day money-back guarantee starting from the delivery date per tracking record. Returns must be in unused, original condition. Return shipping costs are the buyer's responsibility, and the refund is issued less original shipping and handling charges. Customers must contact support before initiating a return.
