How Does It Work?
The Coolizi Cooling Ace uses evaporative cooling — a natural, energy-efficient process. Warm room air is drawn through a water-saturated evaporative cartridge. As the water evaporates, it absorbs heat from the air, lowering its temperature before the cooler air is directed at you through the vent.
This targeted personal-zone cooling means you feel the difference immediately — without wasting energy cooling an entire room. Under optimal dry conditions (below 50% relative humidity), the air output at the vent can be up to 20°F cooler than the surrounding room air.
