When colds and flu are going around, an air purifier for viruses and bacteria is one way to keep yourself and your family healthy. An air purifier can prevent airborne diseases because it can kill or remove cold and flu viruses and bacteria from the air in your home and even boost your immune system by helping you sleep better.

Viruses and bacteria are living organisms known to cause diseases. Bacterial infections can result in strep throat, tuberculosis, and other infections. Viral infections can lead to anything from chickenpox to the common cold and flu. And according to the U.S. Environmental Protection Agency (EPA), harmful airborne germs can also aggravate allergy and asthma symptoms.

More often than not, humans are the main source of airborne diseases in the home and workplace. When someone sneezes or coughs, tiny water or mucous droplets filled with viruses or bacteria scatter, easily entering the air, and then entering your lungs, making you sick. Even without a cough or sneeze, germs can travel up to six feet away. Some viruses stay suspended in the air for hours.

Crowded conditions with poor air circulation, like public transportation and office environments, can also make it easy for cold, flu, and other diseases to spread. Research shows that airflow and ventilation can dramatically impact how diseases spread indoors. The more stagnant your air is, the more likely diseases are to spread. And some bacteria and viruses thrive and circulate through poorly maintained building ventilation systems. This is the case with Legionnaires’ disease, for example.

An air purifier can prevent sickness, especially during the sneeze-filled cold and flu season, by limiting the number of airborne germs. Testing by the accredited CAS Test Technical Servies measured a 99.99% removal rate of the 12 most common viruses and bacteria by the Classic 280i and Classic 480i, including swine flu (H1N1), E. coli, and Enterovirus (EV71).*

"Blueair’s proprietary HEPASilent™ technology captures and kills bacteria and viruses."



Not only do our air purifiers capture harmful airborne viruses and bacteria, but our proprietary HEPASilent™ technology actually kills germs. Internal tests measured 99% of germs were killed by Blueair Classic family** - leaving the bacteria and viruses unviable and unable to reproduce.
