I purchased with the Condo, a Danby Designer product which is TAPED to the window screen. It has two tanks at the back. It stands 33 1/2 inches tall, 2 ft.wide. To move it would involve undoing all the tape that currently holds it to the screen on that window. I would think that it is about 5 or 6 years olds as that is when the condo was built. ron
