Dolphin BF-2070 Box Fan 20-inch 70W 3-Speed

Our review

The Dolphin BF-2070 is a corded electric box fan built around a 70-watt motor, five blades and three speed settings, finished in black. Box fans like this suit people who want a straightforward way to move air across a room, a desk or a work area, and the three speeds let you drop to a gentler setting at night or push more airflow when a space feels stuffy. Before buying, think about where it will sit and whether the cord will reach your socket, since it runs on mains power rather than batteries. Compare it with tower and pedestal fans, which take up less floor space or direct air higher, and with smaller box fans that move less air. Check the voltage stated in the listing against your supply, and consider the noise level a 70W motor and five blades may produce at the top speed.
