8. FILTER
REPLACEMENT
The POWER light flickering continuously indicates that it is time to replace the filters.
Filter life depends on your ambient conditions, we recommend change for at least 6 months once, and
sometimes due to your high dust and pollution it may need change before 6 months.
Replace the filters according to the below directions, and then press the POWER/UV-C button and hold for 5
seconds to restart the system. The POWER light will stop flickering.
1. Turn the air purifier OFF and remove the plug from the socket.
2. Open the front cover from the top by pulling towards outside to unlatch the cover and place it aside.
3. Remove the filter set by pulling the two sides.
4. Insert new combination filter into the unit.
5. Make sure airflow first goes through pre filter, then HEPA filter, finally through charcoal filter.
6. Reattach the front cover of the unit and securely latch into place.
7. Turn the air purifier back on.
8. Press and hold POWER/UV-C button for 5 seconds to reset filter change Indicator.
9. PRE FILTER CLEANING
The air purifier pre-filter should be cleaned every week. More frequent cleaning may be required depending
on environmental conditions. Clean with the brush attachment of your vacuum cleaner. This will remove lint
and dirt.
NOTE:
Only the Pre-filter is washable. And make sure the pre-filter is dry when you fix it back. HEPA
filter and carbon filters are not washable.
