FAQ

A red filter replacement indicator appears on the air purifier when it is time to change filter, after about 6 months of operation.


After you replace your filter, press the center button down to reset the filter light indicator until the red light disappears. It usually takes 7-10 seconds and may take up to 30 seconds depending on the model.
