Comfort Zone Twin Window Fan with Reversible Airflow Control 9 inch Auto-Locking Expanders 2 Speed Fan Dual Fan

The media could not be loaded. I needed an exhaust to keep the house from smelling bad while and after cooking. It works great! The fan noise is tolerable. The stove top exhaust fan is actually more noisy. It's easy to install and remove if I don't need it. I'm happy with my purchase. Read more

Simple Window Fan That Moves Air Well and Gives You Flexible Ventilation I picked this up as a practical way to improve airflow in a room without spending a lot, and for that purpose it does the job well. This is the kind of fan that works best when you want to pull cooler air in, push stale air out, or just get air moving through a room that tends to feel stuffy or hot. What I like most is the reversible airflow setup. Being able to use it either as intake or exhaust makes it a lot more useful than a basic fan. That flexibility matters because the best setup can change depending on the room, the time of day, and the outside temperature. In one situation you may want to pull cooler evening air inside, and in another you may want to push warm air out. This fan makes that easy. The twin-fan design also helps it feel more effective than a small single fan. It moves a decent amount of air for its size, and it is especially useful in bedrooms, offices, kitchens, or other rooms where you want direct ventilation rather than whole-house cooling. I also like that it can be used in the window or set on a flat surface with the included feet, which gives it a little extra versatility. Installation is fairly straightforward, and the expandable side panels help it fit a range of window widths. Once in place, it gives you a simple, affordable way to improve ventilation without needing anything complicated. For everyday use, that convenience is a big plus. I’m currently using MERV 8 filter material on it as an added layer to help with dust and air quality, and so far it has been a useful setup. I do think that adding filter material is something to watch carefully, though, because any added resistance can affect airflow and possibly make the fan work harder. I’ll be keeping an eye on that over time to see whether it causes any noticeable drop in performance, added noise, or strain on the motor. Noise is the main thing to keep in mind. It is not unusually bad for this type of product, but it is definitely more of a functional airflow fan than a whisper-quiet background fan. It works well, but you should expect some fan noise, especially if you are using it in a bedroom or office where sound matters. Overall, this is a practical and versatile window fan that works well for improving ventilation and cooling a room in a simple, low-cost way. It is not fancy, but it is useful, flexible, and effective for what it is designed to do. Bottom line: A handy reversible window fan that does a good job moving air in or out of a room, and it has worked well for my setup so far, even with added filter material, though I’ll continue watching for any long-term airflow or motor issues.

Reasonable price, working good! Read more

My office becomes a furnace in the summer daytime due to concrete jungle/sun hitting straight onto the wall etc. Open windows don't help because the screen mesh I need to keep tiny mosquitos etc out prevents air from noticeably moving in or out. I have an AC unit on one window that works fine but as soon it switches off the temperature is swiftly rising again. I bought this fan because 1) its 4" profile allows it to sit in my window without removing the screen, and 2) it is not a permanent installation, aaand it works awesome for venting my hot computer air directly outdoors. My office is no longer stuffy and humid with recycling air. It's not silent but it is not any louder than my 20" standing fan. Read more

The fan works great can be placed face either direction and still be able to turn it on and off. It has great air flow and it fit perfectly in my basement window. However this fan claims to be quiet it is definitely not, it’s just as loud as a normal box fan. Which sucks because now I have to turn my TV way up to hear it now. Read more

I bought this fan because I was having an issue in my new apartment where the smell of food after I cook would stick to everything and it was driving me nuts. It came the very next day and was quick and easy to install. You just place it on your window on whichever side you want, it’s labeled on each side so you know which way to place it if you want fresh air coming in or exhaust-out. You have to manually take it out of the window and turn it around each time though. The airflow is good and I kept it on high after cooking and the smell was gone fairly quickly. The wire is a bit on the short side so I had to get an extension cord so be mindful of that if you don’t have an outlet close by. Read more

First off, AMZN no longer separates reviews for different models of a product. They now lump reviews of different models together so be wary of this when reading reviews and make sure you search for reviews of your specific model. Now on to the product- The title says that this fan is reversible. That is true. However, my model requires that you open the window, collapse the sides, remove it from the window, rotate the fan 180 degrees, place it in the window, expand the sides, and close the window. This is hardly convenient, especially when you need to do this a couple of times every day due to interior and exterior temperature differentials as the sun rises or sets. Next, fans are typically measured by the diameter from one blade tip to the opposite blade tip. In the case of my fan, that would be 5.5 inches. Next, the blade housing is 7.5 inches, leaving a 1 inch gap between the blade and housing which causes vortices, decreasing airflow. Where they got 9 inches is a mystery. I did not use it for long so I cannot comment on use characteristics. Did it work? Yes. Would I recommend it? Not unless they amend the title and descriptions to fit the specific model so people know what they are buying. Read more
