Sharper Image PROFILE Window Fan with 3 Speeds, Reversible Exhaust Mode, Weather Resistant, Black

While this isn't as strong as I had hoped, it does pass a paper test when the exhaust fan is on. It's really quiet, I don't even hear it anymore. it serves its purpose.

Unfortunately our central air went out and my funds are a bit low right now to purchase a new unit. I purchased one of these fans last year and liked it so much it just made sense to buy two more this year. They take up half the space than our normal window fans and are so quiet on the first speed I didn't notice they were on at all. They also blow out more air than our blade fans. On most high heat days, I use the reverse speed to have the air blowing out during the day and then have the cool air coming into the home at night. Most days this has worked out well keeping our home cool. I haven't been able to figure out how to make the blocks work out for me effectively just yet but it really hasn't been much of an issue.

So far it's been pretty good, measure your window frame first .Pulls air in and out with one button easy to install and take down vary quite .

i like the slim fit to the window. i like that is quiet. there were foam bits to fit next tothe window and fan but there was no instructions on how to put them in correctly. They didnt fit properly lext to the fan.

Nice sleek design. Works as intended.

Works great. Bought this to go in a doorway from our living room where we put in a pellet stove to help disburse the heat through the house. Perfect.

nice air flow, just wish it was more directional

ITS A MUST HAVE!! I AM VERY PLEASED WORTH BUYING. IM IN THE PROCESS OF ORDERING 2 MORE.

I liked the speeds and relative quietness of it. It was awkward to seal in the window. I had to add tape.

This fan is very quite. It can be used in the rain. It has pretty good air flow. Direction can be reversed with the touch of a button.
