The secret behind powerful filtration

Quietly fill your room with more¹ 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 remove 99%² of bacteria 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 removal of viruses and bacteria⁵

Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and removes⁶ viruses and bacteria on the filters using low air draft and plasma charging.

More clean air to every corner of the room⁷

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.
