- Smart features: App control, voice assistant compatibility, and remote operation add convenience, especially for multi-room households.
- Installation and window fit: Check dimensions, installation kit contents, and whether the unit requires a specific window type or frame reinforcement.
- Maintenance: Removable washable filters and alerts help sustain airflow and efficiency. Consider models with easy-clean features.
