C-90B
ELECTRONIC AIR CLEANER

Clean fresh air... your good health and well-being depend on it. But according to the Environmental
Protection Agency, today's tightly-sealed homes and oces can have air that is up to 100 times
more polluted than outdoor air.
An air cleaner is an excellent way to minimize indoor pollutants. The C-90B, Friedrich's second
generation electronic air cleaner, eectively cleans the air for a healthier, more pleasant indoor
environment. We've taken the best and made it even better.
* Based on CADR for tobacco, pollen and dust.
c-90b electronic air cleaner
Top rated and now even better!
The C-90 has been consistently top rated by lead-
ing publications. It quickly eliminates many allergy
and asthma triggers. The C-90B outperforms
every other air cleaner rated for 600 square feet
or less based on its cumulative CADR ratings for
dust, pollen and tobacco smoke removal. The
C-90B’s CADR rating for pollen removal is a full
28% better, and its CADR rating for dust removal
is 15% better than the next leading competitor in
the 600 square foot or less room category.
Quiet operation
The C-90B is quiet and unobtrusive. At
times you may forget it’s running. On
the low fan setting, it runs at 45.89 dBs,
almost as quiet as a PC. This makes it
ideal for bedrooms and oces, as
well as for family rooms and other
high-activity areas.
quickly eliminates dust,
tobacco smoke, pollen,
pet dander and other
allergy and asthma triggers.
Energy efficient
The C-90B is ENERGY STAR®qualied. Products
that have earned the ENERGY STAR label help
protect the environment and cost less to oper-
ate. The C-90B uses about the same amount of
electricity as a household light bulb.
Proven safe & effective
Growing concerns about ionizers and indoor
ozone levels have caused confusion about
what is safe. In standardized industry testing,
the C-90B produced only .014 parts per million
of ozone, well below the UL and FDA limit of
.050 ppm. And the Friedrich C-90B has been
proven eective* by the Association of Home
Appliance Manufacturers (AHAM).

power indicator light

safety interlock switch

self-regulating power supply

How the C-90B works
Easy maintenance
You can keep the unit operating at peak e-
ciency by periodically washing the electronic
cell. Simply lift out the cell and submerge it in a
bathtub or other suitable container. It may also
be placed in an automatic dishwasher.
The pre-lter can be rinsed with water as needed.
The inexpensive carbon lter only needs to be
replaced occasionally, about every three to six
months. Ordering replacement carbon lters is
easy– just go to bestaircleaner.com to place a
secure online order, or call us directly to place your
order by phone. You can also purchase replace-
ment lters from your local authorized dealer.

Virtually eliminates indoor air
pollutants from the air you breathe
Notice a shaft of sunlight as it streams in
through a window. The visible dust and lint
are only one percent of the billions of parti-
cles present. Most are microscopic and will
aggravate allergy symptoms, cause respiratory
ailments and contribute to overall discomfort.
The C-90B eectively works to minimize these
common indoor pollutants:
The pre-lter catches the larger particles as
room air is drawn through the rear grille by a
small yet powerful 3-speed fan.
The electronic cell charges billions of micro-
scopic particles as they pass through a power-
ful electric eld.
Collector plates immediately attract these
“charged” particles.
The activated carbon lter helps remove most
common odors and fumes as the air is circulated
back into the room.

Outperforms other technology
The Clean Air Delivery Rate (CADR) is the standard
by which portable room air cleaners are evaluated.
You will generally see CADRs expressed for the
three most common types of pollutants: tobacco
smoke, dust and pollen. CADR refers to the amount
of clean air provided by an air cleaner during each
minute of operation, measured in cubic feet. The
Friedrich C-90B air cleaner is rated for rooms up to
506 square feet.
With one of the highest CADR ratings in the indus-
try, The C-90B quickly removes airborne contami-
nants as small as .01 microns, approximately 1000
times smaller than the smallest dust speck visible
to the naked eye.
Pays for itself in just a few years
Don’t let the price tag fool you. Yes, the C-90B initial pur-
chase may cost more than some other air cleaners, but
other air cleaners can cost much more to operate.
Compare the costs of a Friedrich C-90B purchased for
$549, and a popular HEPA-ltered air cleaner for $219.
If you run each unit on the medium fan setting for 24
hours per day for ve years, how much will each air
cleaner cost then? In an average year, the C-90B costs
$135 less per year to operate than a typical HEPA-lter
air cleaner. When you add operating costs to the pur-
chase price, the C-90B has a ve-year savings of $675.
