Buying Guide: Key Purchase Considerations

• Room size and BTU: Match BTU capacity to your room size. Larger rooms need higher BTU, while smaller spaces benefit from 8,000–12,000 BTU models to avoid overcooling.
• 3-in-1 vs 4-in-1: Decide if you need cooling, dehumidification, and fan only, or an option that also includes Sleep or Smart modes for energy efficiency.
• Portability vs installation: Portable units require proper venting to an external window; window kits simplify setup and reduce leaks.
• Noise level: Sleep or quiet modes help reduce disturbances at night; check dB ratings if available.
• Smart features: Wi-Fi, app control, and voice compatibility are convenient but rely on stable networks.
• Dehumidification capacity: Consider pints per day if humidity is a concern; higher numbers indicate stronger moisture removal.
• Energy efficiency: Look for CEER or energy efficiency features to manage long-term electricity use.
