Blueair Blue Signature™ Medium Dark Air Purifier With HEPASilent™ Technology

The Blue Signature™ SP3i Medium delivers powerful 7‑stage filtration, advanced odour removal, and whisper‑quiet performance in a beautifully designed form factor. With RealTrack™ filter lifetime tracking, motion‑activated touchscreen controls, and smart VOC sensing, it’s engineered for homes that want deep, effortless clean air.

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.
• [Table‑Top Friendly]: Flat top surface doubles as a side table.
