Care & Usage

The easiest way to clean dust off of internal fan blades is through the use of compressed air. Cans of compressed air can be purchased at most hardware and office supply stores.
No, your fan motor comes fully lubricated out of the box. It does not need to be lubricated or oiled prior to use. We highly recommend against lubricating or oiling the fan at any time.
Try moving your fan to another outlet in a different room. It is possible that there could be a problem with the wall outlet. If your outlet checks out, the fuse within the plug could be blown or there could be a problem with the product. To replace the fuse, refer to your user manual. For further assistance, please contact us via email.
Please see the user manual of your model to provide specific instructions for your model.

Per the instructions provided in your instruction manual, we recommend that you clean the non-electrical parts of your fan frequently to maintain optimum fan performance. Ensure that your fan is unplugged before cleaning.

Tower fans- Clean your fan by using the brush attachment on your vacuum cleaner to vacuum the intake grills to remove lint and dirt. For safety purposes, never open these units for any reason.

Stand /Table/Wall Mount fans- Disassemble your front and rear grills. Reverse the assembly instructions found in the product instruction manual to disassemble the blade parts. The grills and blade may be immersed to be cleaned with a mild detergent and water. Wipe all other parts with a soft damp cloth. Use a mild detergent if necessary. Be sure not to touch the motor. DRY ALL PARTS COMPLETELY BEFORE REASSEMBLING.

Box fans - Using a Phillips head screwdriver, remove the screws on the outside perimeter of the front grill. Remove the front grill, exposing the fan blade. Wipe the blade with a soft damp cloth. Use a mild detergent if necessary. Be sure not to touch the motor or any other electrical components.

Floor fans- Wipe the fan with a soft, damp cloth. Use a mild detergent if necessary.

For all fan types- Clean your fan by using the brush attachment on your vacuum cleaner to remove most lint and dirt. We also recommend using a can of compressed air to clean dirty or dusty interior blades. Compressed air can be purchased at most hardware and office supply stores.

It is best to store your fan in the original or appropriately sized box. If stored fully or partially assembled, the fan head should be covered to prevent dust from accumulating on the blades.
When sleep mode is activated, the fan will cycle through all speed settings in sequential order.
To work properly, the remote control must be in direct line of sight to the fan and within the range of the sensor (range varies by model but usually 10-15 feet).
This function allows you to set the length of time your fan will run before it automatically turns off. The length of time varies from model to model. Please see your user manual for more information.
If your fan includes a remote control, all remotes have a range of up to 15ft, provided a fully charged battery is installed correctly. Note: In order for the remote to work properly, you must point the remote directly at the control panel and ensure that there are no obstructions blocking the space between you and your fan.
Certain models do not have a removable front grill. We suggest utilizing a can of compressed air to remove dirt and dust from blades or by using the brush attachment on your vacuum cleaner to vacuum the intake grills to remove lint and dirt. If your fan does have a removable front grill, please refer to the user manualfor cleaning instructions.

General Information

Intake draws fresh air into the home.
The safety plug is a safety feature that can be found on all of our residential fans. It is a safety device that is designed to cut off electric current to the fan if the device detects a potentially hazardous electrical fault in the fan’s motor or power supply. The fuse is replaceable and replacement fuses can be purchased at any hardware store. For instructions on how to replace your fuse, please refer to your user manual.
This allows the fan to blow air inward or outward with a switch of a button or by remote.
Exhaust is the action of a fan blowing air out of the home.
You can potentially save on cooling costs by turning up your whole-house thermostat and using the breeze from a fan to help you feel cooler.
This grill design has a slight pitch which focuses the air in a particular direction. Usually secondary to the front fan grill, the directional grill can be manipulated to focus the grill in your preferred direction. Some directional grills have the option to turn automatically.
The fan must be manually turned around to change the air direction into the home (Intake) or out (Exhaust).
This versatile feature allows you to set the fan head at multiple heights according to preference and range of motion provided by the fan. Adjustable heights vary by model.
Only available with Twin Window Fans, this feature allows for one fan blade to bring in fresh cool air as the second blade blows warm air out.
Your fan has to use 120 volts and 60 hertz. We do not recommend using any more or less as it will damage the unit.
This fan neck allows the you to adjust the fan head up or down at different angles to focus and direct the air output to your preference.
The quantity of blades does make a difference. The surface area and the angle or pitch of the blades can also affect the output of the fan.
Several fan models come equipped with an additional pole or a removable pole, allowing a height adjustment. The adjustment may allow conversion to a shorter height or a table option (depending on the fan model).
This feature allows the fan head to mechanically turn side to side typically ranging from a 90 or 180-degree motion (depending on model). This feature disperses the air output over a larger area offering whole room comfort.
Air intake describes the fan pulling air from the outside into the room. Air exhaust describes the fan pushing air from the room to the outside. Air exchange describes one fan blade pulling air into the room, while the other fan blade pushes air out, simultaneously.
CFM stands for Cubic Feet per Minute. This is a measurement of how much air the fan moves. Be careful of claims made by manufacturers, as there is no industry standard on how to test CFM. Testing can be done in a wind tunnel, a vacuum, or open area. Each provides a different resistance to the fan blades and cannot be directly compared
If your fan has this option, when breeze mode is activated the fan will cycle through all speed settings randomly, recreating a natural outside breeze.

Stand Fans

Some stand fans are adjustable; however, not all stand fans have adjustable heights. Your fan manual will explain how to adjust or remove poles for different heights.
All Bionaire® stand fans have been designed and tested to not tip over at any secured height, under normal conditions.


A control thermostat is a feature that allows you to manually set and maintain a desired temperature range. The fan will cycle on and off to maintain the desired temperature setting. The setting is based on personal comfort level as the exact temperature in not displayed.
Thermostats are designed to measure the ambient air temperature near the fan and compare it to the temperature setting you selected. The thermostat will respond by turning the fan on or off accordingly. Fans circulate the air, but do not change the existing temperature of the air.

Window Fans

All window fans have an enclosed motor which will allow you to use your fan safely when it is raining. However, we advise that you remove your product from the window during heavy inclement weather as powerful winds could blow water into your home.
Bionaire® window fans are designed specifically to fit virtually all windows. Bionaire® window fans have special features for this purpose, such as extender panels and windowsill holders. Installation of our window fans is designed to be quick and easy, with no tools required. Options available on window fans include the following: electric reversibility for air intake, air exhaust, or even air exchange; thermostats; digital thermostats; temperature displays; and sleep settings for quieter performance at night. Thermostats are particularly useful on window fans, as most people tend to use this type of fan in their bedroom. You can set the thermostat to your desired comfort level. The thermostat will then automatically turn the window fan on or off, in order to maintain your set temperature. This feature is especially welcome in the fall or early spring. As the night air cools down, your fan will turn off, and then turn on again as the morning sun begins to warm your room.
Although Bionaire® window fans are resistant to light rain, if your fan gets wet, we recommend you to unplug it and let it dry before plugging it back in for use.
Window fans can be installed either vertically or horizontally. Please note when installing vertically, the internal adjustable extender panel must be located on the top of the window fan and never on the bottom.
Extender panels can be used to fit window fans into both horizontal and vertical positions. They slide into the right side of your window fans, to allow for a tight fit in your window. Bionaire® window fans come with patented Slider Safe® extender panels, which are designed to provide stability in the vertical position used with a slider window.
No, box fans are not designed with window use in mind. Since they do not provide the secure fit of a window fan, they are more likely to fall out of the window. Box fan motors are also not designed to be rain-resistant, as are those of window fans.
