The simplest type of odor filter is the standard charcoal filter, that requires replacement once its first filtering cycle is completed (i.e. The most advanced technologies can reach filtering efficiency levels of up to 80%.

They have always been used in our kitchens, and our available technologies are the fruit of many years of experience.Īcrylic filters are a not frequently used type of disposable grease filter, and for this reason they must be changed as soon as the system filtering capacity is at saturation.Īluminum or stainless-steel filters are washable grease filters. Grease filters are by now a mature and well-established technology. Grease filters: types and characteristics It is essential that the activated charcoal filter is properly maintained to guarantee a healthy kitchen space.įor both grease filters and activated charcoal filters, technologies are available in various structures and materials to be carefully evaluated according to personal, functional and financial need.

For duct out hoods, a grease filter is necessary, that retains most fatty and greasy substances present in cooking vapors before they are released into the air.The air extracted from the kitchen passes through special filter systems that allow for the removal of both greasy substances and organic molecules, which are the main causes of “bad odors” from cooking vapors.ĭepending on your kitchen hood type, you will need different types of kitchen hood filters: Filtering hoods are more modern extraction systems.The air over the hob is conveyed by an extractor fan into the extraction duct, that expels air outside the home and allows for constant air exchange inside the kitchen.
