“Our electric bill dropped by more than half the first month. It cools our 400 sq ft living room beautifully and I barely hear it on sleep mode. Best purchase of the summer.”

Frequently Asked Questions
How does an evaporative cooler work?
It pulls warm air through a water-saturated cooling pad. As the water evaporates, the air temperature drops naturally — the same effect as a cool breeze off a lake. The chilled air is then blown into your room.
Will it work in humid climates?
Evaporative coolers shine in hot, dry climates (Arizona, Texas, Nevada, California). In very humid regions the cooling effect is reduced, but the fan and air-circulation modes still provide comfort.
How much does it cost to run?
A typical unit draws around 60–110 watts — roughly the same as a light bulb. Running it 8 hours a day costs about $1 per week, versus $25+ for a central AC.
Do I need to install anything?
No. There is no window kit, exhaust hose, or professional installation. Fill the water tank, plug it into any standard outlet, and press start.
How often do I need to refill the water?
Most tanks last 8–24 hours depending on the model and fan speed. Adding the included ice packs boosts cooling for the first few hours.
