The Blueair HealthProtect 7470i Air Purifier provides 24/7 protection against viruses and bacteria. Every component is uniquely designed in Sweden to ensure the HealthProtect™ Air Purifier can quietly provide maximum performance and energy efficiency. The HEPASilent Ultra™ filtration technology combines electrostatic and mechanical filtration to kill 99% of germs and remove dust, pollen, dander, mold, VOCs, and odours. Even when HealthProtect is on standby, GermShield™ technology proactively monitors your room and activates to kill germs and prevent growth of germs on the filter. Unlike other air purifiers that only push clean air to a small part of the room, the SpiralAir™ outlets are designed to deliver 360°, omni-directional, airflow quickly circulating more clean air to every corner of the room. Advanced sensors keep track of the levels of coarse particles like dust, pollen, spores, and ash and fine particles like smoke, viruses and bacteria. These allow you to monitor the pollutants in your home so you can understand how your activities and product choices are impacting your air quality. With smart features like Clean air ETA and real-time pollutant tracking, you can be sure your air is always clean.
