ELECTRONIC FILTER CLEAN REMINDER
These air purifier models each have two electronic filter checks to remind you when to check and replace the True-HEPA filters and the Odor Absorbing pre-filters based on the air cleaner’s hours of use.
When the True-HEPA filter(s) need to be replaced, the light below “HEPA filter” will remain on until it is RESET. You may unplug the air cleaner without interrupting the filter check.
The light below “pre-filter” will illuminate when it is time to replace the pre-filter.
You should periodically check these filters. Depending on operating conditions, the True-HEPA filters should be replaced every 12 months, and the odor absorbing pre-filters every 3 months, especially if there have been heavy odors in the home.
To RESET Either Electronic Filter Check:
Fig. 4 Will illuminate when it is time to clean HEPA filters
When a filter monitor light remains on, it is time to replace the True HEPA or Pre-filter and reset the filter monitor light. With the unit powered on, press the lighted button with the end of a ball point pen with the pen tip retracted and hold for approximately 2 seconds until the light turns off (Fig 4). Depending upon your individual usage (environment and hours used), you may need to check and replace the filters more or less frequently. If the True-HEPA filters are replaced before the filter monitor light turns on, the filter monitor should be reset at the same time.
These cleaning intervals are intended as guidelines only. Performance of any filter media is dependent upon the concentration of contaminates going through the system. High concentrations of contaminates such as dust, pet dander and smoking will reduce the useful performance of the filter.
NOTE: None of the filters are washable. Do not immerse them in water.

MAINTAINING YOUR STAGE 1 ODOR-ABSORBING PARTICLE PRE-FILTER
The stage 1 odor absorbing particle pre-filter not only helps reduce odors, but also helps capture large airborne particles that enter the rear grille. This pre-filter should be replaced every 3 months, as it will become covered with particles and fibers that will reduce filtration performance.
Use the specially designed 
replacement filter, also available where the True-HEPA filters are sold and from Kaz at www.replacementfilters.com or by calling Kaz Consumer Relations at 1-800-477-0457.
