Residential evaporative air coolers use a fan to draw in warm stale air, where it passes over water-moistened pads. This immediately cools the air.
Then evaporative coolers release this cool moisturized air into the space. It's similar to the feeling of feeling a chill when you get out of a pool even on a warm day.
Note: Using an evaporative cooler indoors requires a fresh air source like open door or window.
Evaporative Cooler Benefits
What makes evaporative coolers better than other cooling options? There are several benefits:
Cost-Effective and Small Carbon Footprint
Compared to air conditioners that use compressors and refrigerants, swamp coolers use only water, a fan, and pump to saturate the cooling media and cool your space.
In fact, a 36-inch evaporative air cooler operating for eight hours typically costs less than one dollar to operate, because the only costs associated with operating it are water and electricity.
The evaporative cooling process naturally humidifies dry air - reducing dry air symptoms such as itchy eyes, throat, or skin in dry climates.
Doubles as a Commercial-Grade Fan
Don't add water and use your evaporative cooler as a heavy-duty fan indoors or outside.
