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.
