Frequently Asked Questions

Can Blueair systems trap airborne bacteria?


The answer is a qualified "yes." Bacteria and viruses are trapped in Blueair filters.

No air filtration system is 100% effective at removing 100% of all bacteria and viruses. However, Blueair's combination of mechanical and active electrostatic filtration provides exceptionally high levels of protection. Our HEPASilent® technology traps and removes 99.97% of airborne particles as small as 0.1 micron.


Airborne bacteria and viruses are a common source of respiratory infection and a particular threat to infants, the elderly and those with compromised immune or cardiovascular systems, including people with allergies, asthma, AIDS and heart disease. Some serious infectious diseases are spread through airborne bacteria or viruses, including whooping cough, meningitis and anthrax.

How large are the bacteria and viruses that threaten human health? According to the Pennsylvania State University Department of Aerobiological Engineering airborne pathogens database, health-threatening bacteria and viruses range in size from .018 micron to as large as 1.325 microns. Airborne pathogens larger than 0.1 micron include:

 

- Chickenpox virus (Varicella zoster) at 0.12 to 0.2 micron

- Smallpox virus (Poxvirus variola) at 0.14 to 0.3 micron

- Whooping cough bacteria (Bordetella pertussis) at 0.2 to 0.3 micron

- Pneumonia bacteria (Mycoplasma pneumoniae) at 0.2 to 0.3 micron

- Bronchitis bacteria (Chlamydia pneumoniae) at 0.2 to 0.4 micron

- Meningitis bacteria (Haemophilus influenzae) at 0.2 to 0.3 micron

- Tuberculosis bacteria (Mycobacterium tuberculosis) at 0.2 to 0.6 micron

- Diphtheria bacteria (Corynebacteria diphtheria) at 0.3 to 0.8 micron

- Scarlet fever bacteria (Streptococcus pyogenes) at 0.6 to 1.0 micron

- Otitis media bacteria (Streptococcus pneumoniae) at 0.8 to 1.0 micron

- Anthrax bacteria (Bacillus anthracis) at 1.0 to 1.25 microns
