MAINTAINING YOUR STAGE 1 WASHABLE PARTICLE PRE-FILTER
The stage 1 particle pre-filter helps pick up large airborne
particles that enter the rear grille. This pre-filter can be
periodically removed and shaken to clean it. Alternatively,
it can be rinsed by hand under warm water (Fig. 9). Let
the pre-filter air dry completely before inserting back into
the unit (Fig. 10). If you need to replace this item, please
call 1-800-477-0457 or visit www.kaz.com.
OPTIONAL: Changing the Odor Control Filter
If you have chosen to use the CZ odor control filter that came with your air
purifier, it will lose its effectiveness over time and will need to be replaced.
Call 1-800-477-0457 or visit www.kaz.com to order your replacement odor
If using the CZ odor control filter, it is recommended that you store the original
washable pre-filter in the event that you decided to use it in the future.
To insert it into the unit, simply place securely into the rear grille in lieu of
standard pre-filter as shown in figure 10.
Note: The CZ filter is not washable.
