- Speed and noise: Multiple speeds allow you to balance comfort and noise. Look for models with quiet settings or remote control for convenience.
- Installation orientation: Some window fans are designed for vertical mounting, while others are suitable for horizontal sliding windows. Confirm compatibility with your window orientation and available space.
- Energy and maintenance: Durable motors, easy-clean grills, and removable bug screens help maintain performance and hygiene with minimal effort.
