Summary: I bought it to use in my bathroom and computer room. It works great in the bathroom because I can vent it out the window. When I bought it, there was no mention of needing an outside vent. I seriously considered sending it back because of this. I did try to research the product on other websites, and frankly, there really wasn't enough technical information on any of them. So.. I can't move it to my computer room because of the venting limitation.
