Cleans Your Air From: [Coarse Particles (PM10)]: Dust, pollen, smoke, soot, mould spores, pet hair. [Fine Particles (PM2.5)]: Smoke, pet dander, bacteria, viruses, transport emissions. [Ultrafine Particles (PM0.1)]: Smoke, bacteria, viruses, and fine aerosols from cooking. [Microorganisms]: Bacteria, fungi, protists, and viruses. [Volatile Organic Compounds (VOCs)]: Harmful substances from paints, solvents, and tobacco smoke that can affect your health. [Odours]: Originate from various sources, including food, animals, and industrial processes. How It Works: [7‑Stage Filtration]: Removes 99.97% of airborne particles down to 0.1 microns — dust, pollen, bacteria, viruses, mould allergens. [OdourFence™ Technology]: Breaks down odour gases for 10× better odour removal vs leading competitors. [HEPASilent™ Technology]: Electrostatic + mechanical filtration for high CADR with low noise and low energy use. [Smart VOC Sensing]: Continuously detects airborne gases and chemical pollutants in real time. [Motion‑Activated Touchscreen]: Lights up when you approach; dims when you walk away. [RealTrack™ Filter Algorithm]: Accurately calculates filter life based on usage, fan speed, and pollution levels. [Blueair App Control]: Adjust speeds, set schedules, lock display, track filter life, and monitor air quality. [Double Filter Lifetime]: Patent‑pending filter design extends lifespan to 9–12 months.
