Obviously it works up to minus and plus infinity on one of the axes, possibly the Z-axis, though that’s not guaranteed (maybe it’s a longitudinal or latitudinal moisture remover?)
Nah, it’s the surface area of the extent of the effect. (For greatest volume affected, suspend the device such that its effect can reach, unimpeded, a sphere with that surface area.) Dunno how the physics works; something-something Gauss’s law, I imagine.

That’s actually a proper non-joky perfectly valid and scientific way to justify listing a covered area in square meters rather than volume.
I doubt that’s the actual geometry they used and the surface whose area they list, but none the less it’s still well spotted.
