The dust filter, which collects odorous dust, must be maintained regularly to ensure proper filtration and evacuation of the air.
When the dust filter appears to be saturated with dust, remove the metal grid, and shake the dust filter in a suitable place (above the sink, for example).
Just like the activated carbon granules, the dust filter must be replaced every 3 to 4 months or when the anti-odor filter indicator on the device is lit.
