The BLACK+DECKER 9" Dual Window Fan is about 24.25 x 4.75 x 12.75 inches, according to the manufacturer. This makes it compact enough to fit most windows and simple to install or remove.
It comes with two 9-inch blades that can work together to either pull air in or push air out, but you can't control them separately. Some folks mentioned in our research that they wish it had separate intake and exhaust controls, but many still find it effective for circulating air and quiet enough to use at night.
It's also lightweight and easy to move around. If you're looking to improve ventilation and perhaps cut down on air conditioning use, this fan could be a solid option.

The BLACK+DECKER 9" Dual Window Fan does a good job of cooling and ventilating a room, though it's not without a few quirks. According to the manufacturer's description, it has dual 9-inch blades that either both pull air in or both push air out. You can't set one to intake and the other to exhaust, which has confused some people who thought it had independent controls for each fan.
Our research pointed out that this surprised and disappointed a few folks, like Heather, at first. Despite that, many still find it quite effective and easy to use. It reverses easily between intake and exhaust modes, just not in a mixed way people might expect.
Advantageously, this fan is light and straightforward to set up, qualities users appreciate. For example, Jay G. mentioned that it's "nice, lightweight, and easy to fit into a window," making installation and removal hassle-free. Another user, Julie, simply said, "I love this fan," which echoes the general positive sentiment.
If you need a fan that's simple to install and effectively refreshes the air by either pulling it in or pushing it out, this one seems to fit the bill nicely. But if you’re after a fan that can do both intake and exhaust at the same time with separate fans, you'll need to look further.
Yep, the BLACK+DECKER 9" Dual Window Fan can do both intake and exhaust.
According to the manufacturer's description, you can flip it between pulling fresh air in or pushing stale air out. But keep in mind, both fans have to be in the same mode—they can't work in opposite directions at the same time.
So you can't have one bringing air in while the other pushes air out. Some folks have mentioned this was a bit of a letdown, especially if they wanted continuous air circulation. If that's a dealbreaker, you might want to check out other models that offer that feature.
But overall, people have said it does a good job of improving airflow and cooling, especially at night since it's pretty quiet.
For general ventilation, this fan should work well for you.
