ELECTRONIC FILTER CLEAN REMINDER

This model air purifier has an electronic filter check to remind you when to check and clean the HEPA- Type filters based on the air cleaner’s hours of use.

A red LED light will illuminate when it is time to clean the filter.

You should periodically check the filter. Depending on operating conditions, the filters should be cleaned every 6 months to a year.

To RESET the Electronic Filter Check:

When the filter check light remains on, it is time to check/clean the HEPA-Type

filters and reset the filter check, if needed. With the unit powered on, insert the tip of a ball-point pen or paperclip into the hole next to the LED filter check light and hold for approximately 5 seconds until the light turns off (Fig 5). Depending upon your individual usage (environment and hours used), you may need to check and clean the filters more or less frequently. If the HEPA-Type filters are cleaned before the filter check light turns on, the filter check 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: The HEPA-Type filters are not washable.

•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. 6). Repeat along the entire surface of the HEPA-Type filter.

•Note the filter may still be discolored even after cleaning it. This is acceptable and will not affect performance.
