During the dog days of summer I decided to buy an extra fan to help move some air around in my apartment. After shopping around a bit I found the** ****Lakewood**** 20'' Box Fan** at Walmart. If you have purchased a number of fans you probably realize that some are better than others. The **Lakewood 20'' Box Fan **is, in my experience a good balance between being inexpensive yet good enough to operate quietly and efficiently. This fan has a square shape, is 20" across, has 5 blades, and 3 speeds. There are little plastic feet to keep it from tipping over (which you have to install - no big deal). One oddity is the plug, which can be detached from the back and is located about half-way up the back of the fan. This fan really moves a lot of air and does so quietly. There are no rattles, squeaks, and any vibrating sounds are minimal. Although it's too big for my windows it works fine in front of a sliding glass door and can easily be moved around (it's lightweight). One drawback to the fan is that the plastic parts seem really cheap. The blades are really thin, the handle on top in a solid piece of inflexible plastic, and the knob (located on top) is small and cheaply made. My concern is that the cheap plastic parts may not hold up over time. UPDATE: This fan was OK for about 4 years but is now falling apart. The little feet keep falling off, it rattles a lot, and the plug (which can be detached) keeps coming loose. We're going to have to buy a better one.
