Best Evaporative Air Coolers of 2020
It is essential to find ways to beat the heat during the summer months. Besides air conditioners, portable ACs and fans, another option is evaporative air cooler. So, what is the evaporative air cooler? How does it work? And what makes it better than other cooling options?
What is an evaporative air cooler?
An evaporative air cooler is a device which lowers air temperature through evaporation. Unlike cooler air conditioners replying on vapor-compression to cool air, evaporative coolers utilize the natural ability of evaporation to lower air temperature.
How does an evaporative air cooler work?
An evaporative cooler cools air through evaporating water. It includes a fan and a water-soaked pad where the fan draws warm, stale air inside the unit and then passes it over water-moistened pads to be cooled. Then it releases this cool air into the space. It’s like when you get out of a pool on a hot day and immediately feel a chill as the outside air cools the water on your body. It should be noted that using an evaporative cooler indoors requires a fresh air source like open a door or a window.

- Cost-Effective Option: a 36-inch portable evaporative air cooler operating for eight hours typically costs less than one dollar, which is almost three times cheaper than traditional cooling costs.
- Environmentally-Friendly: evaporative air cooler use motion and water to cool the air, which is a natural process and doesn’t add ozone-harming pollutants or other chemicals to the environment.
- Good for Health: The evaporative cooling process will naturally humidify the dry air, reducing dry air symptoms such as itchy eyes, throat and skin.
