People who favor fans over air conditioners like to feel a house breathe. A good window fan is a real blessing to a fan person, and doubly so if that fan can be set to blow in two directions. Double the benefits yet again if that window fan has two fan blades, each of which can be set either in or out. The Holmes HAWF3095 window fan has those quadrupled benefits, and then some. There are two 3-speed fans in the unit, each of which can be set for air intake or exhaust, or for air exchange, when one blows in and one out. In addition, there's a programmable digital thermostat and timer, so the fan can shut off automatically when nights get too chilly. And of course there is a simple on/off mode, especially good with the air exchange configuration. Air direction is set by using the sliding switches located above each fan blade. The mode button is used to turn the fan on and control the speed. The mode button also cycles through three automatic thermostat settings: Auto High, Medium, and Low. There are two additional temperature adjustment buttons to fine-tune the thermostat to a personal comfort level. In addition, a timer setting allows the fan to be programmed to turn on and off at one-hour increments over a period of as long as 16 hours. The HAWF3095 fits most windows, whether it be a casement, slider, or double-hung style. The fan can function either horizontally or vertically, and there are two 3-inch extenders that can slide on at either or both ends to help tailor the fan to most any window. Always unplug fan before cleaning. Use a soft cloth moistened with a mild, nonabrasive soap solution. Do not use gasoline, paint thinner, or benzene as a cleaning solution; also do not allow water to drip on or enter fan housing. The Holmes HAWF3095 window fan measures 25 by 13 by 5-1/2 inches. (For certain casement windows, a specifically designed bracket may be required; upon request, Holmes customer service supplies this bracket free of charge, along with installation instructions.) Holmes provides a five-year limited warranty against defects in material and workmanship under normal use conditions.--Garland Withers
