Dont confuse this air cooler with an air conditioner. Its more compact, cheaper to run and requires no outside venting. It works by sucking in warm, dry air and passing it over a damp honeycomb filter. As water evaporates, air cools and an internal fan disperses it around the room with 3 fan speeds: sleep/normal/natural. Move from room-to-room on easy-roll castors. Operated by a touch switch or remote control (included). 80W. 4L cold water tank. 7.5hr timer. Mains lead, L1.5m. H57 xW26.5 xD25cm.
