Smart Features and Controls
Remote control, Wi-Fi connectivity, and voice assistant compatibility improve convenience. Set schedules or adjust temperature remotely for optimized use.

Especially for bedrooms or home offices, select units with quiet operation, ideally below 55 dBA, to minimize disturbance during use.
Installation and Maintenance
Consider ease of installation and accessibility for regular maintenance, such as filter cleaning or condensate draining.
