- Installation Ease: Consider models that come with installation kits or accessories to simplify setup, particularly for challenging window shapes.
- Control Options: Remote control, programmable timers, and smart Wi-Fi connected features add convenience and improve energy management.
- Air Quality Features: Washable or reusable filters that trap dust, pollen, and pet dander help maintain clean air in small spaces.
- Additional Functions: Features such as a dehumidifier mode, multiple fan speeds, and adjustable air direction enhance comfort customization.
- Window Seal Kits (Optional): Consider seals or vent kits designed for small windows or portable ACs to maximize cooling efficiency and prevent warm air leaks.
