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.
It is normal for deposits
from tap water to collect in
the Remove and Rinse™
tray.
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 avoid
harmful chemical interac-
tions.
• First, turn off and
unplug the humidifier. Wait
at least ten minutes for the
humidifier to cool.
• Remove the No Drip™
water tank by grasping the
handle and pulling straight
up.
