Presenting a great, new range of portable air coolers exclusively from MasterKool. This stand alone, quiet and reliable unit is a great alternative to a fan cooler. Ideal during the warm summer months, the iKool-80 Plus provides a cost effective, efficient and reliable cooling solution for homes and small offices alike. Introducing the new ‘Mosquito’ function, this new function will let off a high pitch audio (you will not hear this) which will deter Mosquitoes and other small insects away from the cooler! *Not to be confused with an air conditioner, an evaporative air cooler is a fan that also benefits from additional humidifier and cooling functions. Using the humidifying function an air cooler will use cold water vapour from the water tank to reduce heat in the air which is flowing through the unit, whilst in cooling mode the addition of ice packs can help to produce even cooler air.  Air coolers require a constant flow of air from an open window/door to efficiently work.
