Filters room air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 698 ft² room to effectively lower particle levels and maintain a comfortable environment in extra-large areas of your open floor plan, studio, or basement.
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 an advanced DualProtection filter for the ultimate combination of gas and particle removal. Filters airborne bacteria, viruses, and allergens like pollen, dust, and mold, as well as gaseous pollutants like chemicals and odors from pets, cooking, and smoking.
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.
DualProtection filters use coconut carbon to effectively filter out airborne gaseous pollutants like smoke, volatile organic compounds (VOCs), exhaust, smog, odors, and chemicals up to 4x faster than other Blueair carbon filters.
