Bionaire BW2300 Twin Window Fan with Remote Control

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

It also has an Automatic mode that controls the fan's operation until the desired temperature is reached. This feature is not ideal since it will have the fan starting and stopping every 2-3 minutes when the temperature rises back to above the desired temperature.

Altogether, I am very satisfied with this fan, even though I do not use the Automatic feature. It is exceptionnaly quiet I find and the air flow features get the job done in no time.


Powerful, quiet, and well worth the price   July 6, 2006

My living room (approx 12'x16' and open to the kitchen) was always the last room to cool down after a hot day. It sometimes took most of the night to cool despite standing a powerful fan in front of it. The Bionaire BW2300 cools it in half the time it used to take.

~Edit: My statement that this fan cools my liviing room in half hte time I once did is inaccurate. If the outside temp is lower than inside, the fan cools the living room in just a couple of hours.~

It also does a great job circulating air when its hot out (and in) to keep the room from feeling stuffy.

I have not experienced the temperature gauge problem that other reviewers have. The temp gauge on mine works well.

~Edit: The thermometer reads the temp of fan's exact location, not the room's temperature. For example, in the afternoon sun, mine consistently registers a much higher temp than the actual room tempature. When it is colder outside at night, it registers a slightly colder temp than the room temp. ~

Is it really quiet? Yes! I have a Vornado fan, which is quite quiet for a fan. This is even quieter (although not silent).

To accomodate different window sizes, this model comes with a built-in extender, and two add-on extenders. The fan with extenders isn't large enough to fit my 38.5" window width. I could order another add-on extender from the manufacturer, but stuffed a wash cloth in the gap instead.

What comes in the box? The fan, two extenders, two AAA batteries and the remote.

~Edited 7/28/06:
I bought a second one for my bedroom. Its thermometer is completely inaccurate and overstates the temperature until the outside temp is about 75 degrees.

The slats which the air blows through are fixed on this model. So I cannot direct the air onto (or away from) a particular area of the room.~


I really LOVE the remote control   April 17, 2004

I've been running this fan for a week. This is the only window fan I found that came with a remote control. It compares pretty well with all the other Holmes and Honeywell competitors with adjustable speeds, the ability to adjust fan direction electronically, and an adjustable thermostat. But the main selling point is the ability to do all of this while sitting at my desk or lying on the bed. One little gripe is that the on/off button on the remote control sticks a little and sometimes skips a few settings as a result of it, but I got the hang of making it not stick when I press it.

The noise level is quite acceptable to me especially at the lowest setting. It blows very smoothly. My previous cheap window fan spun like an F-15 engine at the lowest setting, and I had to turn it around to change the fan direction, so this new fan is a godsend. I hope it holds up during the blistering hot summer days.

One other thing - it also makes an excellent air freshner when you set the fan to blow the air out or on air exchange mode. I'll be selling my Honeywell air filter.


Great cooling fan...   June 24, 2004

I live in Orange County, California, near the beach, so the air is generally cool outside. The sun warms the inside of the house, so the trick is getting the cool air into the warm house. This fan is great for that.

NOISE: There are three speeds. Low and medium are fairly quiet. High is louder.
AIRFLOW DIRECTION: There are three options- BOTH IN, BOTH OUT or EXCHANGE (one fan in, one fan out). The only mode that really cools the room is BOTH IN, but it works well (it works even better if you open the bedroom door so there is no resistance to airflow).
SETUP: installation was easy, but note that you have to have a narrow window that slides up and down, because there is presumably no way to fit it into a tall window that slides sideways.

I recommend this product. The only caveat is that I have only had it for a few days, so I have no idea if it will be durable. The five year warranty gives some comfort.

Durable fan so far. Have owned for over a year and run several hours a day. The remote is a plus where most other fans do not have.Would recommend spending the few extra bucks on this unit. Will buy another when this one decides to retire.
