Blueair Blue Signature Mini Air Purifier, 2-Pack, HEPASilent Filtration & Auto Mode

Bring compact air purification to two spaces with the Blueair Blue Signature Mini Air Purifier 2-Pack. Each unit features four-stage HEPASilent filtration, designed to remove 99.97% of airborne particles down to 0.1 microns, and a real-time five-color air quality indicator.

Built-in sensors monitor PM2.5 levels, while Auto Mode adjusts fan speed in response to changing air quality. Select from four fan speeds, adjust display brightness, or set a timer to suit your daily routine.
