The Best Window Fans

The powerful, dual-blade Bionaire Twin Reversible Airflow Window Fan has routinely clobbered every other window fan we’ve tested, and we have happily used this model for years. However, we’ve seen new complaints pop up with this model in recent summers, noting some problems that we’ve experienced ourselves in re-tests. Window fans meet a unique need, but they are notoriously weak products. So even though this is the best of the lot, those who are shopping for a window fan should ask themselves whether they need to get one in the first place.
