The Elica CFC0141571 is a set of activated charcoal filters designed for range hoods operating in recirculation mode. These filters focus on air purification by trapping grease and neutralizing cooking odors before the air is released back into your kitchen. This pack includes a pair of mod58 filters, ensuring you have both components needed for a complete replacement. To maintain consistent air quality and filtration efficiency, it is recommended to replace these carbon elements every three to four months. They are specifically compatible with the Elica Elite 14, Ciak, and Era models, providing a precise fit for those who cannot install an external ventilation duct.
