Answer: 
Not at all easily. This fan has no mounting holes, brackets, or other hardware, it's intended to sit on a flat surface like the floor or a windowsill. Not to mention that it would not work properly without significant clearance in the back (where it's pulling air from). Monting it within a few inches of a wall would put a heavy strain on the motor and greatly reduce the airflow. And since the controls Read More
Not at all easily. This fan has no mounting holes, brackets, or other hardware, it's intended to sit on a flat surface like the floor or a windowsill. Not to mention that it would not work properly without significant clearance in the back (where it's pulling air from). Monting it within a few inches of a wall would put a heavy strain on the motor and greatly reduce the airflow. And since the controls are on top of the fan, I really can't imagine how you'd control it, unless you just set it to one speed and then used an extension cord with a remote switch or something like that.
I don't mean this in a rude way but, basically, "if you have to ask", you probably won't want to try. It would be more than a minor "project" even for someone with some DIY experience and a degree of McGyver-esque ingenuity.
I don't know if Home Depot carries them, but fan manufacturers do make wall-mountable, oscillating fans. They're (obviously?) quite a bit more expensive than this item, but their design makes that more or less a given. It sounds like one of those would be your best bet. Read Less

Answer: 
You would have to custom mount it with straps or something. The frame is plastic so you can just screw mounts or straps wherever is needed. Be sure you can reach the knobs.

Answer: 
But is it the same fan? That one has complaints of being noisy. This one is supposed to be super quiet. One would suppose that would change the CFM. Does it?

Answer: 
You will have to check their website for the specifics. According to the product description -Save-Smart design costs less than 2-cents per hour to run. Doesn't say if that is on low med or high.
