Review on 🌬️ Lasko W09560 Bluetooth-Enabled Twin 9-Inch Window Fan for Bedroom Indoor Home Use, White - Intake & Exhaust Motors with Thermostat and Timer by Emily Baker

We are using this fan on a double casement window. We were a bit hesitant as most manufacturers only show installation in the lower half of a dual gimbal. But we installed this in the top half with no problems by turning the block upside down so the channels of the block lined up with the window frames (see photo). This setting is of paramount importance to us as we want to extract warm air from the room above. Our window is 42 inches wide, so we'll cover the extra space with a piece of plywood. We chose this device because it has the highest rating for low noise. And we can confirm the low noise level of the fan. Our cat sleeps in this window and continues to use it as a bed with the fan on, so she's fine with that too. It keeps the room comfortable on hot days, which we couldn't achieve before purchasing this fan. The Bluetooth app and controls work great - they're simple and intuitive. We can control fan on/off, fan direction, activation speed and temperature from our ground floor. The only downside to our setup is that the temperature gauge is also upside down; very minor inconvenience. We recommend this unit to others considering a window fan because of its efficient heat dissipation, relatively quiet fans, and Bluetooth remote control. The extra $20 we spent on this unit over similar fans was well worth it.
