Quiet operation is crucial for bedrooms. We measured sound output; aim for under 30 dB on low speed.
Compact design matters for small spaces. We favor units that are less than 8 inches wide and lightweight.
Ongoing costs add up. We checked availability and price of replacement filters to ensure value.
Look for low wattage consumption. Most models under 50W are efficient for continuous use.
