Blueair Air Purifiers Technology - HEPA and
Electrostatic Air Filtration
The diagram above shows the major components
of Blueair 501s. The other Blueair units vary slightly but
use the same basic technology.
Dirty airflow from the room enters through the bottom and lower sides of
the Blueair units. This is driven by a high efficiency Blueair fan
that was specially developed in conjunction with Siemens Corporation.
The dirty airflow passes ionizer brushes
that are carefully placed in the center of the housing. This serves to
charge the particles like dust, dander, pollen, and other particulates.
The airflow that is still carrying
charged pollutants is moved through the HEPASilentTM
filters. These filters are made from nontoxic polypropylene rather then
the typical paper. In addition to providing an ideal location for
mechanical and electrostatic filtration, this material is waterproof so
it provides no location for bacteria to grow.
Now that the pollutants have been removed
from the airflow it is returned to the room through the top and sides of
the air purifiers. Since the airflow is returned through
such a massive area, 6-times that of most air cleaners, it produces
less noise.
Note that the structure of these air
purifiers is steel to also
damp noise and that there is a conveniently located 4 speed switch on
the side of the air purifiers.
