Classic 290i with DualProtection filter

Completely filters the air in a 26m² 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 26 m² room to effectively lower particle levels and maintain a comfortable environment in bedrooms, living rooms, and home offices. Integrated sensors auto-adjust to current conditions in your environment to ensure air quality remains at a healthy level. Available with an advanced SmokeStop™ is a 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.
