Arizona has one of the best climates to own an evaporative cooler. Depending on when the monsoon weather moves in the evaporative cooler can usually be used until late June, early July. One benefit of using the evaporative cooler is the cooling process. The evaporative cooler naturally humidifies dry air – reducing dry air symptoms such as itchy eyes, throat, or skin. Another benefit of the evaporative cooler is the cooling process. This process is a natural process that is cooling the air using motion and water, which in turn, is not adding any harmful ozone-harming pollutants or chemicals to the environment.
