Answer 1

It's basically a lot of desiccant and a fan to blow air from the room over the desiccant and back to the room.

You can have the fan facing any way you want, as long as it circulates air over the desiccant and back to the room.

Remember that you have to replace the desiccant frequently. For that reason, they are not very popular.
