Modern aluminum filter is an integral part of a kitchen hood. Perfelli grease filters are present in every hood and allow you to effectively clean the air, as well as prevent engine contamination and prevent grease particles from settling on furniture. Unpleasant smell, grease, dust and soot, during the operation of the hood, remain on the filter, preventing their spread and contamination of the kitchen. This is why the aluminum filter should be cleaned well as the hood is used.
