If you're looking for a simple and cost-effective way to cool a room without relying on air conditioning, a dual-blade window fan is a practical solution. Here’s a balanced review based on typical performance and features:Easy Setup: Most models are designed to fit double-hung or sliding windows and come with adjustable panels to create a secure fit. Setup usually takes only a few minutes and doesn’t require tools.Two-Way Airflow: The ability to use the fan for intake or exhaust is a major plus. This helps circulate fresh air from outdoors or remove warm indoor air—especially effective in cooler evenings.Quiet Performance: Even on higher settings, noise levels are generally low, making it a great choice for use during sleep or work.Energy Savings: It’s much more efficient than an air conditioner and ideal for those wanting to reduce electricity use.

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.

Took off a Star as I wasted a half hour trying to get their Apps to work on my Samsung....If you have an Android Phone don't bother w/ their Comfort Apps.Go immediately to the Smart Life app.It set up in under a minute.You have full function in this App.For Echo.....Changed name, then opened Alexa and it had already found it!Alexa will NOT change Mode, but it will change Off/On and Speed.Use "Alexa set (name of YOUR fan) speed 1,2 or 3.If I find an Echo 'Mode' work around I'll Update.Fan works GREAT!!! Moves a TON of Air.

Wow. this is awesome! A while ago I had my roof redone, and the roofer replaced my skylight with a domed one that has been heating my kitchen so much that plates and things in the kitchen actually felt warm to touch. I installed this fan in an upper sash window that is next to & below the skylight and now my kitchen feels cool! I wish I had thought of doing this a year or so ago.

1st, these are great fans. I have one that is remote and not wifi and I love it so I thought I would like the wifi enabled even more. While the fan is still a great quality fan, the setup for wifi was a 2 hour nightmare. And it does not come with a remote as I thought it did. ☹️ I wasted 2 hours trying to connect this to Alexa. No go. After more time wasted researching on internet, I finally stumbled across someone who said to use the Smart Life app instead. Bingo. It connected in about 3 seconds. It is ok but not ideal. With the Smart Life app, you can turn it on and off, and you can change the speeds, all through Alexa. But you cannot change the mode from cooling to exhaust or circulate, with Alexa. You would have to push the buttons manually. This will work for me for now, because I am using it in a bedroom window at night, and I wanted to be able to turn the fan on or off, or up or down, if I woke up in the night and it was too hot or too cool. I'm going to check and see if I can purchase a separate remote that will work with this. Great fan, but just be aware.

Best decision ever. I have a very small wondow on the third floor that basically gets no airflow. This window fan helps tremendously getting the hot air out and at night bringing the cool air in. It is simple, light, and works really well. It is a bit loud, but nothing is perfect. Best purchase ever.

Works great, it’s exactly what my bedroom needed to cool down, i always have my bedroom door shut so the fan just recirculated hot air, but now i’m able to exhaust out the hot air and keep in the cold, i use it with my ac infinity air vent they make a great duo.

Honestly it’s not any louder than any other window fan I’ve purchased.The pro- the remote is on my phone. No more losing the remote or manually turning on and off. I can turn it on from anywhere which is really awesome.The fan is powerful and does work.The con side- I don’t have a screen in my window, so I was hyped about this coming with covers. I’m not sure who the design artist was on this- but the latches and hooks don’t match up. Meaning the netting is far too long on the 1 corner on each side and won’t stay latched. But it does in 2 corners of 3 on each side. I have only had it for less than 24 hours. I’ll update again if there are other pros or cons that arise.One other person reported the vent doesn’t work and you manually need to switch it around. This is not true. The app “Living Comfort” does it all.
