Comfort Zone Living Comfort Smart Wi-Fi Reversible Twin Window Fan with Removable Cover and Bug Screen, 9 inch, 3-Speed, Expandable, Timer, Compatible with iOS/Android/Alexa/Google Assistant, LC310SWT

vent a room quickly draws cool air in if you want or can do both at the same time. This is my second one the other one lasted about four years and still works but needs a good cleening lol

I bought this fan to integrate with Home Assistant to control air flow into a sunroom. It is recognize immediately by Smart Life once plugged in. Using the official Tuya inegration, only on/off is exposed. But if you use the "Tuya Local" integration, you can control everything, including fan speeds and modes. It works quite well for its purpose. The noise level is on the loud side, around 48db at low setting and 54db at high setting. There is some humming from the AC motor. But I think that's true for most window fans. I will probably put some more padding around it to reduce the noise a bit.

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.

The sides could extend longer. Moves hot air quick

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 Amazon, 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.
