We recommend that you
clean the humidifier once
a week, or more often if
you:
• have hard water,
• notice a build-up
of impurities, or
• detect unpleasant odors.
Using DuraSept
™
Humidifier Bacteriostatic
Treatment (#AC-802) will
help control the growth
of bacteria, algae, and
odors and help extend
the life of the Natural
Cool Moisture
™
Filter.
NOTE: THE USE OF
OTHER WATER TREATMENT
PRODUCTS MAY CAUSE
DETERIORATION OF THE
FILTER OR DAMAGE THE
HUMIDIFIER, THEREBY
HINDERING THE HUMIDI-
FIER'S EFFECTIVENESS.
DO NOT USE SOAP,
DETERGENTS, OR
ABRASIVE CLEANSERS.
Cleaning involves two
steps: SCALE REMOVAL
and DISINFECTING.
Be sure to perform these
in the proper order to
