Review: Amazing buy - 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.
Review: A good fan for certain uses - I’ve had this Wi-Fi enabled, 3 speed, reversible fan unit installed now for 7 days in the summer, in a room used as a home office. The unit works as advertised. The Comfort Zone app and my iPhone get along nicely. I have the unit installed in a modern double-hung window. I did not use the bug screen. The window width required that the unit’s expandable panels be pulled out. While the panels pull out easily, they are not as wide (vertically) as the fan portion and thus leave narrow gaps above and below the pulled-out panels which, in some locations, would require use of the bug screen to exclude insects (so far, not yet a problem for me in a usually buggy environment). Also, the panel latches are flimsy and do not hold the panels fully out. I used small wood wedges jammed into the panel tracks to hold them out at the distance needed. As for noise level, the unit makes a notable ‘beep’ when changing speeds/modes and always makes a ‘hum’ sound which, surprisingly, does not change with fan speed; it is just there when the unit is on, loud enough to be noticeable but low enough to be ignored in all but a very quiet environment, such as in a bedroom where I don’t believe I could use this unit due to the constant hum (but its fine in my office). Consistent with the product description at desertcart, the 2 small fans move enough air to affect the room in which the unit is installed but not enough to affect other rooms. This true even if the fans are on all night at high speed. To achieve multi-room cooling, you would a fan which moves lot more air. Bottom line, the noise level and air moving ability are about what one should expect from a small unit while the pull-out panels leave gaps and the panel latches not well designed.

## Features

- SMART APP-BASED CONTROL: Take full command of your environment from your smartphone. Use the user-friendly Comfort Zone app (iOS and Android) to power the fan on/off, adjust speed settings, and switch between airflow modes from anywhere in your home.
- VERSATILE 3-IN-1 DESIGN: Enjoy ultimate ventilation flexibility. Switch between Cooling mode to pull in fresh air, Exhaust mode to remove stale air and odors, or Circulate mode to move blades in opposite directions for superior air distribution.
- ADAPTABLE WINDOW FIT: Designed for a wide range of spaces, the auto-locking accordion expanders adjust from 23-1/2" to 37" wide. This ensures a snug, secure, and stable fit in most double-hung and slider window frames.
- CUSTOMIZABLE 3-SPEED PERFORMANCE: Choose from Low, Medium, or High speed settings to perfectly match your cooling needs. Whether you need a gentle nighttime breeze or a powerful gust to refresh a large room, this fan delivers.
- PROGRAMMABLE SMART TIMER: Use the integrated timer function via the app to schedule your fan’s operation. Set it to pre-cool your bedroom before sleep or turn off automatically after you leave for work to save energy.
- REMOVABLE BUG SCREEN: Breathe easy while keeping the pests out. The fine-mesh bug screen prevents insects and outdoor debris from entering your home, ensuring your incoming fresh air is clean.
- PROTECTIVE FABRIC COVER: Keep your fan in top condition. The included removable cover shields the unit from dust and environmental elements when not in use, prolonging the life of the dual motors.
- SPACE-SAVING SLIM PROFILE: The compact, low-profile design of this 9-inch fan allows it to provide powerful circulation without obstructing your view or taking up valuable floor space.
- RELIABLE DUAL-BLADE SYSTEM: Featuring two high-efficiency fans working in tandem, this unit is engineered to move air quickly and quietly, making it ideal for bedrooms, kitchens, and home offices.
- EASY PLUG-AND-PLAY SETUP: No complicated installation required. Simply expand the side panels to fit your window, lock them in place, and plug into a standard outlet to begin enjoying smart, localized cooling.

## Questions & Answers

**Q: Do you like this item?**
A: So-so window fan. Misleading to fraud listing! Since you must click for sellers, Amazon staff likely compiled  the listing. It isn't 9" blade. 9" ONLY IF YOU COUNT THE CENTER PIECE. Actual blade is 6". IT DOESN'T Have "ELECTRONICALLY REVERSABLE MOTORS". I was surprised the box says "Manually reversible". In all my years, I Never encountered a "reversible fan" that meant you can reverse the entire fan! Of course! You can do that with ANY house FAN EVER MADE! This listing is FRAUD.

**Q: can one fan blow out and the other in?**
A: The fan has three modes, and desite what other reviewers erroneously posted A) ond of the three modes is Exchange, where one fan draws outside air in while the other fans expells room air out, So yes one can blow out and the other in  B) you do not need to know how to use the remote control to change modes.  There are buttons on the fan with which you can control fan speed and mode.

**Q: Will this fan fit a 24 inch wide window?**
A: no. the fan is almost 25" wide.

**Q: Can this fan be used in slider windows?**
A: Yes, this heater can be used in slider / casement windows.  In this case the fan will be vertical, and bottom accordion will mostly likely be closed, and the top accordion will be extended to seal off the opening.

### ⭐⭐⭐⭐⭐ WiFi function is a game changer
*by C***U on December 3, 2023*

I bought this for its WiFi function. I already had one from different brand with exact same dimension and almost identical to the model with remote but no WiFi. I put the fan in the window in the our bathroom in master bedroom. In winter, we close the door and all windows in the room in night except for the opening of window to accommodate this fan. It serves a few functions. 1st, clears out the moisture inside from shower; 2nd, get cool air from outside during summer; 3rd, get fresh air from outside to reduce CO2 inside. The fan functions mechanically identical to the one I had without WiFi. It’s a decent fan. However, with WiFi, it can run automatically when the situation calls. It supports the Smart Life app available in both iOS and Android. I had the app already connects to sensors (a CO2/temp/humidity sensor connected to a Bluetooth gateway compatible to Smart Life), I can set the fan to turn on (at desired mode and speed) during night time when the CO2 in the room exceeds limit (I choose 1200ppm), and turns it off when it drops down to lower level. Now it automatically runs to refresh the air during the night and shuts off itself when done. It works really well, and you can do similar setup with temperature or humidity with sensors compatible to the Smart Life app. By the way, although it does not come with remote. You can easily use your phone anywhere in the house or just ask Google or Alexa to turn it on/off. I highly recommend to purchase WiFi model instead of others.
