Keep your tumble dryer at its most effective with this replacement Asymmetric Filter Cassette Assembly. The filter in your tumble dryer helps ensure that fibres and lint from your clothes are filtered out during the drying process, and a working filter will help save on energy bills compared to a tumble dryer operating with a worn filter. If one of the filters has become clogged, your tumble dryer won’t work at its optimum best, so replace it to get your appliance back to 100%. Please check model fit list to ensure this part is correct for your model.
