I bought the air cooler for summer because this is much better than ac however it will not give the ac effect but is efficient in both maintenance and power consumption.
The only thing is we have to change the water at frequent time otherwise it will start giving the bad smell. But we can use this in both normal air flow and chilled air flow.
Kenstar is very old product in this platform. My colleagues too suggested this brand because they are using the same product.
the only thing is the fan is in vertical mode so that you will not get spread air flow and also the swing is very limited area to cover.
