Blueair300/Blueair400
F I LT E R S
Patented HEPASilent™ technology makes the
Blueair 300/Blueair400 incredibly quiet. Units
come with one HEPASilent™ particle filter
(installed):
Particle Filter – includes 1 particle filter that
removes dust, pollen, bacteria, pet dander, mold
spores and other airborne particles. The particle
filter is made of polypropylene, which mechani-
cally filters out airborne particles. To maximize
filter effectiveness, particles are negatively charged
before reaching the filters.

Filter – contains active carbon
and is recommended for use in rooms where
heavy gaseous pollutants such as cigarette and
cigar smoke or other VOCs (volatile organic com-
pounds, such as household paints) are present.
On first use you may notice a slight odor from the
active carbon; this will dissipate quickly.
For optimal performance Blueair recommends
that you replace filters every six months.
We offer a convenient Filter Subscription Program
(not available in all countries). For information or to
place an order, contact your local dealer or Blueair.
IMPORTANT! Use only Blueair filters to ensure
proper functioning and to qualify your unit for full
warranty coverage.
