400 series

The series 400 air purifiers from Blueair are available in electronic or classical models and are suitable for rooms from 20 to 40 sqm (215 to 430 sq ft). They are endowed with a patented HEPASilent filter. The volume of air treated every hour is impressive! Indeed, the air purifier inhales air on all its back face and returns it cleaned of all its impurities by the top. Its extremely silent fan, ionisation and 3-stage progressive filters makes it a formidable tool against bacteria, pollens, and other allergens. They can be equipped with a Smokestop filter (activated charcoal), which eliminates tobacco smell. They all obtained very good results in CADR tests (Clean Air Delivery Rates). We recommend you to change the filters every 6 months.
