Evaporative Swamp Cooler Buying Guide
In low-humidity areas, swamp coolers can provide a natural and energy-efficient means of cooling. Swamp coolers, or evaporative coolers, work by passing outdoor air over water-soaked pads, which then causes water to evaporate into it. This cooler air (anywhere from 15 to 40 degrees Fahrenheit) is then directed into a home, allowing the swamp cooler to provide cooling comfort by lowering the ambient temperature.
When deciding on a swamp cooler, always pay attention to the unit's air moving capacity, as well as installation and maintenance requirements.
Also, be aware that swamp coolers may require a bit more maintenance than portable air conditioners such as replenishing the water supply, draining the unit, and keeping the cooling pads clean. But in spite of this, one of the main benefits of a swamp cooler is the fact that it can efficiently cool an area by using one third the amount of electricity of conventional air conditioners.
