2. Important Safety Instructions
Please read and save these important safety instructions before using this product to reduce the risk of fire, electrical shock, or injury to persons.
- Always unplug the fan before moving, cleaning, or performing any maintenance.
- Do not operate any fan with a damaged cord or plug. Discard fan or return to an authorized service facility for examination and/or repair.
- Do not run cord under carpeting. Do not cover cord with throw rugs, runners, or similar coverings. Arrange cord away from traffic area where it will not be tripped over.
- Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage the fan.
- To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use on soft surfaces, like a bed, where openings may become blocked.
- This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
- Proposition 65 Warning: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
- The fan is equipped with Lasko's trusted safety fuse technology.
- While the fan features a Weather-Shield motor for window use, ensure electrical connections are protected from direct moisture.
- Using filters with a MERV rating significantly higher than the included MERV 10 filter may reduce airflow and potentially strain the motor. It is recommended to use MERV 8-10 filters for optimal performance and motor longevity.

4.2 Filter Installation (if not pre-installed)

4.3 Placement
Position the fan on a stable, flat surface. For optimal air circulation and purification, consider placing the fan 1 to 3 feet in front of a window rather than directly on the windowsill. This can enhance the volume of air drawn into the room. Experiment with placement to find the most effective setup for your environment.
5. Operating Instructions
The Lasko Air Flex features a simple mechanical control knob for operation.

6. Maintenance and Filter Replacement
6.1 General Cleaning
