Checking the Air Filters

When the change filter icon lights up, this is simply a reminder to check the air filters. The icon turns on sooner or later depending on how often you use your air purifier. It does not necessarily mean it is time to change the filters. If the change filter indicator has turned on, please remember to reset the air purifier after checking the filters by pressing the black reset button inside the vent on the side of the air purifier.

When Should I Replace the Air Filters?

It is recommended to change the air filters every 6–8 months. However, you may need to change your filters sooner or later depending on how often you use your air purifier. It is important to watch out for the following signs of expired filters:

    • Increased operating noise
    • Decreased airflow
    • Clogged filters
    • Increased presence of odors

Replacing the Air Filters

1. Unplug the air purifier and remove the back cover.

4. Install the True HEPA filter into the housing. Making sure the pull tabs are facing out
