The customer is either confused or spoilt for choices available in an evaporative air cooler, as the market is flooded with ever-increasing varieties and multi-brand invasion in this category. The Evaporative Air Coolers are also available for purchase online, however, a short and crisp checklist as given here will help in finding out the best Air Cooler to buy:
· How thick are the cooling pads as the thickness level indicates the cooling efficiency directly since thicker pads absorb more water and therefore cooling is sustained for a longer period?
· Fan size and air throw can give an idea of how much area the cooler can cool up to. Bigger coolers will have larger-size fans with low rpm but with higher air throw.
· Fan speed regulator gives the ease to operate Evaporative Air Coolers to one’s comfort level.
· Water level controller saves you from the tension of checking and monitoring excess seepage of water, as you can preset the same.
· The ability to run on an inverter gives you the flexibility to run the machine to back up the power supply in case of power failure.
· Lastly, auto air swing provides the possibility of spreading the air to the wider area rather than the uni-direction airflow.
