Lasko 2155A Electrically Reversible Window Fan

The Lasko 2155A Electrically Reversible Window Fan gets high marks from users for its powerful airflow, which many say can effectively circulate air throughout a house. Most users also say that the fan is quiet and fits easily in their windows. Users praise this fan's ability to exhaust smoke and odors, as well as hot air, and they like the fact that it can switch from air intake to exhaust with the touch of a switch. Another nice plus is the fan's StormGuard feature, which makes it possible to close the window behind the fan for safety (or to keep out rain and insects). Because this fan has only a single set of blades (rather than the two sets included with many window fans), it can't be used for air exchange. It's also on the expensive side, and we read several complaints about its durability. Many users say that the switch knob has a tendency to fall off, and several complain that the fan shakes at high speeds. Because this fan is quiet, it won't make a good white noise machine for the bedroom; if this is a major drawback for you, consider the Lasko 3300 20-Inch Wind Machine (*Est. $40).
