Twin Window Fan with Dual Speed, Reversible Airflow, Auto-Locking Expanders, and Removable Cover – Portable Window Exhaust and Intake Fan

【Dual Speed Settings】
Choose between low airflow for gentle cooling or high airflow for powerful ventilation. This twin speed window fan gives you the flexibility to customize comfort in any room.

【Secure Auto-Locking Expanders】
Designed for windows from 22.25" to 33" wide, the accordion-style expanders lock into place for a snug, secure fit. No batteries required—just plug it in and enjoy fresh airflow.

【Reversible Airflow Function】
Switch easily between intake mode to pull in cool, fresh air, or exhaust mode to push out warm, stale air. This feature improves ventilation, air circulation, and overall indoor comfort.

【Protective Removable Cover】
Includes a fabric cover that shields against bugs, dust, and debris. When not in use, it prevents hot, humid air from entering, helping maintain a comfortable environment indoors.

【Portable & Versatile Design】
Use it as a window fan or tabletop fan—thanks to built-in feet and a convenient carrying handle, you can move it easily between rooms for cooling wherever you need it.
