Buying Guide

- Noise level: For bedrooms and nurseries, prioritize low dB ratings and sleep modes to minimize disturbances.
- Controls and smart features: Decide between mechanical controls, remotes, apps, or voice integration based on preference and ecosystem compatibility.
- Maintenance: Consider washable filters, ease of drainage for portables, and auto-defrost/defog features in heat-capable units.
