Ideal for a space 12feet by 12feet such as a small bedroom , i fill 4 x 2 litre plastic bottles and put them in the fridge and use them to top up when the little orange ball lowers to the middle of the gauge .
The only problem for me is that the manufacturers / designers failed to include an additional 3 filter pads which are needed to replace the pads that need to be removed for cleaning and drying otherwise i am very happy with InstaChill Air Cooler
