Cleaning the grease filter ensure that the hood filtering system is maintained in the best possible state and guarantees long-term durability and correct hood operation. The grease filter should be washed by hand or in the dishwasher (on a low temperature setting) with neutral detergents (short cycle). The filter should be washed at least once a month and based on your individual needs. We also recommend periodically replacing it to improve the grease capturing capabilities. Always check how to wash the filter in the product instruction manual.
