Classic 490i with DualProtection Filter

Completely filters air in 40 m² room every 12,5 minutes​. Filters room air at the industry-recommended rate of 4.8x an hour (or about every 12,5 minutes) in a 40 m² room to effectively lower particle levels and maintain a comfortable environment in master bedrooms, living rooms, and playrooms. Integrated sensors auto-adjust to current conditions in your environment to ensure air quality remains at a healthy level. Easily adjust settings remotely from your smartphone and tablet via the Blueair app, or connect with your Amazon Alexa enabled device for voice control. Comes standard with a particle filter to remove airborne allergy and asthma triggers like pollen, dust, pet dander, mold, smoke, bacteria, viruses, and more. Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers.
