We found the Holmes Window Fan which features both Intake and Exhaust options. One is installed in our kitchen window to Exhaust hot air when cooking and Intake cool air the rest of the time. Other fans are installed in bedroom windows. The one on the cool side of the house is set to Intake cool air and the other one is set to Exhaust hot air. This provides constant circulation and makes our home very comfrontable.

The only complaint we have is cleaning. One side of the fan comes completely off for easy cleaning. The other side is attached to the motors. We have to unscrew the motors and put them in zip lock baggies while we clean the rest of the fan. This could be easily corrected by making both sides independent of the motors.

Even with this inconvenience, this is the Best product we have found to keep our home cool and comfortable in a humid climate.

"The amazing no-breeze fan!"
The breeze provided by this fan can only be likened to the movement of air inside a sealed jar sitting in the sun: the air moves, but that movement is only detectable at the molecular level. With both motors of this fan running on high intake, you can feel the air move only if you're seated directly in front of it, at a maximum distance of about 24 inches. In fact, when I plugged in this fan for the first time and turned it on, I at first thought that the fan was set on outake (i.e., pulling air out of the room); instead, the most gentle imperceptible breeze was wafting directly at me. This fan is very quiet; however, no fan would be quiet as well, while the breeze coming through the window would be about the same. To properly summarily evaluate this product, I wanted to give it no stars, to indicate the fan's complete abandonment of its function, but alas, ... rating system's lowest rating is one star. Purchase this product only if you wish to circulate air inside a small box.
