Pro-Kool Evaporative Cooling Works! Many people mistakenly believe they live in a place that is too humid and hot for a Pro-Kool evaporative cooler to be effective. But the laws of physics dictate that as the temperature rises, relative humidity falls.
A review of weather data from hot weather regions shows that even in the most humid climates, midday relative humidity levels are well within the range where Pro-Kool can provide heat relief. Humidity levels may start the day in the 90% range during the cool morning hours, but at 90 degree F. and above, it's almost impossible to have humidity levels above 70%.
