Bionaire BW2300 Twin Window Fan

Bionaire BW2300 Twin Window Fan with Remote Control
With a remote control for convenient adjustment, this double window fan draws in fresh, cool air from the outside or exhausts stale, hot air from inside. It can also do both simultaneously, because each of the two fans can be set independently to draw in or exhaust out, allowing the unit to exchange inside and outside air. Operable either manually or automatically--with its thermostat turning the fans off and on to maintain a selected temperature--the unit has three speeds, electronic controls, and an LCD screen showing the selected temperature and the room temperature. The remote control (two AAA batteries are included) alters speed, manual/automatic operation, air-flow direction, and temperature.

The twin fan is designed to fit double-hung, vertical-slider, and casement windows. A built-in 7-inch extender and two 3-inch extenders permit custom fitting for windows from 24 to 37 inches wide. Because the unit is lightweight plastic it can be moved easily from room to room. The fans have six blades and measure 8-1/2 inches in diameter. Overall, the unit is 13 inches high, arrives fully assembled, and carries a five-year warranty against defects. --Fred Brack

Great window fan.
I've had this fan more than a year now and decided to write a review after having bought a Honeywell window fan. I guess I didn't really appreciate this bionaire before I used the other fan, Honeywell. Honeywell window fan is so loud that I can't use it for my bedroom. So I decided to use it for the living room, but now I have to turn up the TV volume higher and get irritated by the noise. But, bionaire's quite and circulate air very well. I really recommend this bionaire fan to anyone comparing between Honeywell and Bionaire.

Great fan, powerful and quiet, but don't count on temp control
As others have said the temperature control auto mode is useless. However I didn't buy it for that feature so I don't care. Poor production quality though.
This fan was very easy to set up and operate. I appreciate the ability to change the air flow direction. The fans are both quiet and powerful. The remote works well.
Our house is well insulated with 6" exterior walls. Once it gets hot from the sun coming in through the large glass surfaces it is hard to cool off even though the evening outside air is cool. This window fan pulls warm air out of the house allowing us to open windows in strategic places to draw in cool air. The first time we used it it paid for itself.
