CLEANING/REPLACING THE HEPA-TYPE FILTERS
This model is equipped with long-life HEPA-Type filters. You have the option of
cleaning your HEPA-Type filters or replacing them, depending on your personal
preference.
To Clean Your HEPA-Type Filter:
• Air purifier should be turned off and unplugged prior to cleaning filters.
• Remove the rear grille from the air purifier by pushing down on the release
tab at the top of the grille and pulling the grille away from the unit.
• DO NOT USE WATER OR OTHER LIQUIDS TO CLEAN THE HEPA-TYPE FILTER.
• Remove filters from the unit. DO NOT IMMERSE FILTERS IN WATER.
• It is recommended that you use a vacuum cleaner that has a HEPA filter built into it. If a HEPA filter
vacuum is not available, you should vacuum your HEPA filter outdoors to keep the particles from getting
recirculated in the air in your home.
• To vacuum-clean the filter, hold the filter and run a vacuum cleaner with a nozzle or brush attachment
along the filter to pick-up the dirt and particles (Fig. 8). Repeat along the entire surface of the HEPA-
Type filter.
• Note: The filter may still be discolored even after vacuum cleaning it. This is acceptable and will not
affect performance.
• After vacuuming the filter, place it securely back into the air purifier housing and snap filter grille into
place.
• Press and hold the "Filters" button to re-set the indicator light.
