5 replacement filters for our outer wall air vents ALD and ALD-S. Dimensions (Ø): 140 mm
Filter change
If a filter needs to be changed, this is signalled by the LED on the device lighting up continuously in red. To do this, remove the cover of the inner screen, then the dirty filter can be removed & disposed of. Insert the new filter into the filter frame holder and snap the cover of the inner screen back into the "open" position. In addition, the filter change display can be reset by pressing the event button on the integrated control unit for three seconds. Our regenerative filters can be cleaned 4-5 times without any problems before they should then be replaced. The filters are available in packs of five directly from the webshop.
