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.

help control the growth of
bacteria, algae and odors
and help extend the life of
the Natural Cool
Moisture™ filter.

UCTS MAY CAUSE DETERI-
ORATION OF THE FILTER
OR DAMAGE THE HUMID-
