“Installed temporarily in a window. Works well to vent moisture and smell. Accidentally cooled down porch when left on with central air. Wish it came with its own window shield.”

“Easy to install cause u can get a 4” holesaw easy. The noise level is a little high for the amount of air or moves but not terrible. I put a clothes pin on the flaps to improve air flow.”
