While typical air purifiers simply push dirty air through a filter, our HEPASilent™ technology combines two filtration technologies. The result is more clean air at a faster rate, with whisper-silent operation that consumes less energy than a lightbulb.

HEPASilent Ultra™ is Blueair's 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, mould, VOCs, and odours. HEPASilent Ultra™ delivers 50% more clean air³, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration.


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 kills 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.
