Why Choose Protect 7440i?

• Quietly fill your room with more clean air

  HEPASilent Ultra™ is our most advanced filtration technology ever. Every component is uniquely designed in Sweden to provide the maximum performance and energy efficiency. This patent-pending technology combines electrostatic and mechanical filtration to kill 99%² of germs and remove dust, pollen, dander, mold, VOCs, and odors. HEPASilent Ultra™ delivers 50% more clean air³, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration⁴.

• 24/7 protection against viruses and bacteria

  Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and kills⁶ viruses and bacteria on the filters using low air draft and plasma charging. A gentle stream of air then ensures no new growth of germs.

• More clean air to every corner of the room

  Unlike other air purifiers that only push clean air to a small part of the room, the patent-pending SpiralAir™ outlets are uniquely engineered to deliver 360°, omni-directional airflow - quickly circulating more clean air to every corner of the room - so you breathe clean air wherever you are.

• Air quality numerical display

  An intuitive 5-color indicator bar gives quick updates on particle and gas levels, and a numerical display quantifies the levels for PM1, PM2.5 and PM10 particles.

• Designed with smart features

  Designed with smart features like Clean air ETA⁸ and real-time pollutant tracking, you can be sure your air is always clean.
