The best part of this air cooler is it low noise function and three side honeycomb padding for extra cooling. The water pimp also pumps enough water so the cooling will be more efficient. 36 Liters is large enough so we dont have to fill water often. Cooling is good enough for one medium sized bedroom. Overall it’s a very good aircooler when compared to other top brands. The defects are, it doesn’t have a tray for ice cubes and the water inlet is very small.
