Sharper ImagePORTAL Window Fan with 3 Speeds, Reversible Exhaust Mode, Weather Resistant, Window Fan For Kitchen, Bedroom, Home, Low Profile, Black

I have been looking for a decent squirrel cage style window fan for years. Although this is a little on the pricey side, I think it is well worth the investment. 1st) They look to be quite well built. I love that the design of the grill, which is in a uniform rectangle. This makes it possible to cut a block of foam (preferably gray in color ~ which I did) to block the flow of air from the outside air when the fan is not in use by sandwiching into the sides of the unit in front of the grill. 2nd) I like that it was easy to apply a screen with duct tape to the outdoor side of the air intake to keep out insects. 3rd) The fact there is no remote control is a bonus because it's one more thing to loose. 4th) The electronic buttons are intuitively easy to use and it's a big plus that you can use it to exhaust your indoors if you burn the toast. 5th) Even on high the fans are relatively quiet. On the low settings they are nearly inaudible. 6th) I love they are weather resistant, that said I will likely construct a roof out of plexiglass to shield the unit from storms as I intend to have them available for use all year round, although in the heat of Summer I'll forgo the hot humid outdoor air for AC. 7th) They are offered in a black color which has two advantages. First they will show little in the way of particle dirt accumulation compared to the typical white window fans which look like they need cleaning after one week use. Second, they essentially trap light which is great for the bedroom when you do not want to be disturbed by sunlight in the early morning hours. 8th) The air pattern generated by the fan is more of a directed narrow beam that excites the air thereby moving the air in the room around in contrast to the typical prop style fan which leaves stagnate zones within the living space.Cons? Maybe slightly less CFM per dollar to other window fans. That said, I am convinced that the CFM generated by this fan has greater efficiency in the way that it creates a beam of air that excites or moves around the air in the room to a greater scale.I purchased 2 because I love the design and function of the unit.Recommended.

HELLO EVERYONE, I AM HERE TO GIVE A 2 YEAR UPDATE ON THIS BEAUTIFUL WINDOW FAN THAT I PURCHASED 2 YEARS AGO, AND I PURCHASED TWO OF THESE WINDOW FANS IN BLACK FOR $79.99 EACH FOR MY LIVING ROOM AND IT WORK'S GREAT!!!!!!! NO NOISE AT ALL AND ALTHOUGH THE AIR IS NOT STRONG I LIKE THE LIGHT COOLNESS AND QUIET SOUND I GET FROM IT I GET VERY RELAXED WHEN I AM FEELING THAT AIR IN MY LIVING ROOM BUT THIS WINDOW FAN IS THE BEST FAN I HAVE EVER HAD AND ALTHOUGH I DON'T LIKE TO REMOVE IT FROM MY WINDOW BUT WHEN IT'S TIME FOR ME TO REMOVE IT I WILL CLEAN IT USING FANSTASTIC SPRAY AND HOT WATER ON THE BLADES AND THEN PUT IT AWAY WHEN THE SUMMER IS OVER BUT WHAT I LIKE THE MOST ABOUT THIS FAN IS THAT IT HAS BEEN WET SO MANY TIMES FROM THE RAIN STORM AND IT STILL CONTINUE TO WORK! IN PERFECT CONDITION AND I AM PROUD TO SAY THAT THIS FAN STANDS BY IT'S NAME SO I AM VERY HAPPY TO SAY THAT I STILL HAVE BOTH FANS AND THEY ARE WORKING PERFECTLY FINE NO PROBLEM AT ALL SO DON'T LOOK AT THE PRICE YOUR GETTING SATISFACTION

I will start with the bad about this fan. There are foam inserts to block off the window area that you will not be using. You do have to finagle those inserts in a way to have adequate coverage in the window gaps. There are no instructions on how to use these foam inserts.Also, your screen needs to be open depending on the gap that you have between your screen and your window. Mine is about a 3 inch gap and that’s not enough clearance to leave the screen closed. So the concern for bugs to enter at will is there, though it hasn’t happened as of yet.There is no duel function on this fan, it cannot blow air in and exhaust simultaneously.The good:It’s small. I have a small window that does not open too far. So the slimline is appreciated so that I can actually have a fan in my window. The exhaust is adequate. I use this fan in my home office as an exhaust fan. My Home office is a small room, and the fan works adequately in exhausting smoke. There doesn’t seem to be much residual smell of cigarette smoke left behind at the end of my shift. The noise level of the fan is not too overwhelming. Doesn’t it interrupt or distract me from my work. I could see it being a nice white noise machine if someone is looking for that.I have used this fan for about 80 hours and so far am satisfied with this purchase.
