What matters in a bedroom

• Size it one step up. A bigger unit on low is quieter than a small one on high.
• Sleep mode. Look for a low-noise setting with the display lights off.
• Running cost. It'll run eight hours a night, so filter prices matter. Compare costs.
• Door shut. It cleans the room it's in.
