Sturdy Appearance
This fan has a nice, sturdy appearance to it and is actually a bit heavier than most window fans at almost 14 pounds. It doesn’t have an easy grip carrying handle, which makes its weight a bit cumbersome, but it snaps into place firmly without a lot of fuss and looks pleasant enough if it is just left in place constantly.

One of the more convenient design aspects of the BW2100 is that most of the front finger guards are vertical, which cuts down on dust build up which can be frustrating to clean because it does not disassemble easily.

It has a decent air flow for a medium size room, and can be easily changed from exhaust to blow or air exchange by flipping the individual slider buttons on each fan. The speed settings cycle all the way through the 6 options, 3 for manual and 3 for auto, so this is slightly less convenient than simpler switches if you don’t intend to use the thermostat very much, but it’s not an overt hassle.

A more serious drawback of this fan is that the heat from the motor tends to affect the temperature readout, and therefore turns the fan off at a higher ambient room temperature than it should. This inaccuracy can vary a by as much as ten degrees between units of the same model, so the temperature might need to be set somewhat lower than the actual room temperature desired, depending on the unit.

Overall, the BW2100 is a very good, solid mid-level fan. It blows very well, handling a lot of air for its size and volume, making it perfect for small and medium rooms and can definitely handle the difficult job of exhausting cooking odors from a kitchen.
