In a comprehensive study conducted by the Hammacher Schlemmer Institute, this is the tabletop fan that generated the greatest air velocity, the best measure of a fan's cooling power. Its 47-watt motor spins a four-paddle, 12" metal blade at up to 1,550 RPM, moving up to 55% more air than other models and ranking highest for air velocity at all three speed settings, yet it operates more quietly than most. The fan head oscillates 80° and tilts to 15° to precisely direct air flow for maximum comfort, and its blade is enclosed in a brushed metal cage for safety, with a front grill that can be removed easily for cleaning. Unlike lesser fans made with plastic components, the best tabletop fan features a brushed metal stand and housing, a clear 1/4" thick glass base that measures 11"-diam. for stability and has rubber feet to protect tabletop surfaces, and an integrated metal carrying handle. 5 1/2' cord plugs into AC. Minor assembly required. 19" H x 13" W x 10" D. (13 lbs.)
