My future mother in law has purchased this air cooler unit for the baby nephew :)! It’s on offer from $3xx to $299 ! Rental of air coolers can be pretty expensive and if any of you are interested in purchasing one which you can keep for your future home, I suggest getting this! Value for money because rental of air cooler unit could cost you about $100 per day.
It will be nice to have air coolers at the side of the pelamin or at the back as it won’t be as stuffy/hot as compared to having fans.
