Buying Guide

• Room size and BTU: Match the unit’s BTU to your room (roughly 8,000 BTU for up to 350 sq ft; 5,000–6,000 BTU for smaller spaces). Consider ceilings and sun exposure which can affect cooling load.
• Window compatibility: Check exhaust hose length and window kit range. Small windows may require trimming or adapters; ensure the kit supports your window type (sliding, casement, etc.).
• Modes and controls: Decide if you want 3-in-1 or 4-in-1 features. Dehumidification can lower humidity levels in hot climates, while sleep and timer modes improve nighttime comfort and energy use.
• Noise level: If a quiet environment matters (bedrooms, study rooms), prioritize units with lower decibel ratings or “sleep” modes that minimize display and fan noise.
• Smart features: Apps, voice control, and remote operation can simplify daily use and scheduling. Verify compatibility with your smart home devices if that’s important to you.
• Portability: Look for caster wheels and lightweight design if you need to move the unit between rooms or store during off-seasons.
• Maintenance: Removable, washable filters and easy drainage (continuous drainage options or internal tanks) reduce upkeep and improve efficiency.
