“At Blueair we are proud to be an industry leader in performance testing,” said Jonas Holst, Chief Product Officer. “Blueair has built its position as a leader within the air purification industry by 25 years of independent third-party testing of all innovations. Today there is no surprise that a fear of COVID-19 is driving demand for air purifiers, and as such, our commitment as a brand needs to deliver honest, factual, results on live SARS-CoV-2 virus that consumers can trust.”

In addition to removing the airborne SARS-CoV-2 virus from the air, Blueair’s most advanced air purifier ever, HealthProtect™, is the only air purifier to provide 24/7 protection against viruses and bacteriaiii, allowing you to feel reassured about the air your family breathes each day.

HealthProtect™ state-of-the-art technologies include:

  • HEPASilent Ultra™ combines electrostatic and mechanical filtration to remove 99.97% of viruses and bacteriaiv, dust, pollen, dander and moldv, while removing VOCs, and odors. Once caught in the filter, this unique technology then kills 99%vi of germs. HEPASilent Ultra™ delivers 50% more clean air, uses 55% less energy and makes 10% less noise than traditional true HEPA filtration.vii
  • GermShield™ proactively monitors your room when your air purifier is on standby and activates to kill germs and prevent growth of bacteria on the filterviii using low air draft and plasma charging. A gentle stream of air then ensures no new growth of bacteria.
