HEPASilent™ filtration technology
All Blueair air purifiers feature exclusive patented HEPASilent™ filtration technology for outstanding
filtration efficiency, as well as extremely quiet and energy efficient operation.
The typical air cleaner traps particles using only one type of technology. The secret of Blueair is the
use of special filter material and an ozone-free electrostatic ionizer that charges particles so they are
electrostatically attracted to the filter material.

Air is drawn in to the purifier where the particles pick up an electrical charge. The charged particles are then effortlessly
captured in the special designed filter.
Blueair uses a progressive filter structure. Most filters from other manufacturers use a thinner filter that
consists of the same size of fiber throughout. Blueair filters have millions of ultra-fine fibers in different
sizes with decreasing size the deeper in the media. Thus, the name progressive. This leads to that the
filters resist loading or clogging and continue filtration at peak performance levels longer.
To give an example we have illustrated filtration through a gradient structured filter with different fiber
sizes (1), representing the Blueair filters, and another filter with only one fiber size (2) as traditional
HEPA filters. Notice the airflow before and after the filter:

Blueair’s gradient structured and progressive filter consists of different sizes of fibers, allowing maximum airflow and resistance
to clogging while keeping high efficiency.
