Amazon Basics Twin Window Fan (9-inch)
Ranked #2 in Best Window Fans
Amazon Basics Twin Window Fan (9-inch)
2 sources$34.36as of Oct 16

A basic 9-inch twin window fan with two speeds and manual controls. Bob Vila tested it, rated it 4.3 out of 5 and named it Best Bang for the Buck; TechGearLab tested it, scored it 66 out of 100 and named it Best Window Fan on a Budget, measuring 755 CFM of airflow. Both found the same main drawback: to switch between intake and exhaust you have to take the fan out and turn it around.

Strengths
  • — Bob Vila rated it 4.3 out of 5 (Best Bang for the Buck); TechGearLab scored it 66/100 (Best Window Fan on a Budget)
  • — TechGearLab measured 755 CFM, tied for second-highest in its test, and 1.27 newtons of thrust
  • — Bob Vila found installation takes minutes; TechGearLab gave it its highest installation sub-score (9.0)
Watch-outs
  • — No thermostat or temperature-based shut-off
  • — TechGearLab says it cannot stand vertically, and its CFM readings reflect lackluster air movement for larger spaces

Bionaire BW2300-N Twin Window Fan
Higher ratedRanked #1 in Best Window Fans
Bionaire BW2300-N Twin Window Fan
1 source$60as of Oct 17

The Bionaire twin window fan pairs two 8.5-inch reversible blades with a digital programmable thermostat, three speeds and a remote, and fits windows 24 to 36 inches wide. TechGearLab named it its best overall window fan with a score of 70/100, praising single-degree thermostat control and low noise at full speed, though it measured only middling air movement. The Spruce also made it its best overall pick for its remote and independently reversible fans, while Reviewed called it its best value but found its wind speeds on the lower side of average. It suits bedrooms and home offices where quiet, automatic temperature control matters; anyone who wants strong whole-room circulation should look at a larger fan.

Strengths
  • — Thermostat sets in single-degree steps, with clear, intuitive controls
  • — Quiet at full speed: TechGearLab measured 50.1 dBA, well below most rivals
  • — Each of the twin fans can be set to intake or exhaust independently
Watch-outs
  • — Modest airflow: Reviewed's wind-speed results sat on the lower side of average
  • — Starts on high, beeps at every button press, and limits display dimming
  • — Remote needs a clear line of sight to the fan's sensor

How they stack up

Amazon Basics Twin Window Fan (9-inch)

TechGearLab measured it at 755 CFM, tied with the Bionaire BWF0910AR and above the Genesis A1WINDOWFAN's 669 CFM, but the Bionaire adds a remote and electric reversing. Bob Vila gave it the same 4.3 out of 5 as the Vornado Transom, which costs more and adds a remote, a digital touch panel and push-button reversing. Unlike the Genesis and Holmes HAWF2043, it has no thermostat.

Bionaire BW2300-N Twin Window Fan

TechGearLab measured the same 754.5 CFM airflow from the Bionaire and the Amazon Basics Twin Window Fan (9-inch), but the Bionaire adds a thermostat, a remote and push-button exhaust, where the Amazon Basics must be turned around in the window. The Vornado Transom measured quieter in the same tests but moved far less air (248.3 CFM), and The Spruce notes the Genesis A1WINDOWFAN Twin offers temperature settings without a remote.
