These things work great. They are unvented though, so might not be legal
in your neck of the woods. I got one because it's quiet, it doesn't
stink, and it doesn't blow dust around. I used it in my wood shop until I
moved, and put in a vented wall unit with a little more horsepower.

Oh yeah, and they're good for backup because they don't need power.
