If you're a DIY enthusiast and enjoy deepening your knowledge of various components, particularly those in kitchen hoods, then you're in the right place. I've already discussed how metal filters work in another article, but here I'd like to explain in more detail how these filters are made and what enables them to capture grease and oil vapors effectively.
As you may already know, metal filters for kitchen hoods play a crucial role in trapping grease and oil particles released during cooking, thereby protecting the motor and maintaining the hood's efficiency.
Below, I'll explain in detail their composition, materials, types, and how they work.
Let's get started!
Grease filters, also known as metal filters, are commonly made from aluminum or stainless steel (inox).
Aluminum is widely used for its lightness and resistance to corrosion, while stainless steel is chosen not only for its greater robustness and durability but also for aesthetic reasons, as it gives the hood a more professional and refined appearance.
These filters consist of multiple layers, which may be metal meshes or lamellas, through which the extracted fumes pass. The labyrinth design of the meshes is essential for trapping grease and oil particles within the filter, preventing them from reaching the hood’s motor.
To go into more detail, a typical aluminum filter comprises several layers of overlapping metal mesh. The number of layers can vary depending on the brand and model, but generally, there are around 3-5 layers. Each layer serves a specific function, and not all meshes have the same width or hole shapes:
The thickness of aluminum filters can vary, usually ranging from 8 mm to 10 mm, depending on the filter's structure and efficiency.
Now, I’d like to explain in more detail the two main types of metal filters for kitchen hoods: mesh filters and baffle (or labyrinth) filters. Each type has different characteristics and uses.
These are made of multiple layers of overlapping metal mesh. This type of filter is very common in domestic hoods and is ideal for trapping small grease particles. It is versatile and easy to clean.
These consist of a series of slanted baffles positioned at regular intervals, creating a maze-like pathway. These filters, also known as labyrinth filters, are often used in professional kitchens, such as in restaurants. Their structure allows them to trap a larger amount of grease than mesh filters, making them ideal for heavy-duty use.
The baffle design also facilitates the easy drainage of grease, reducing the risk of clogging.
When the hood draws in fumes and vapors produced during cooking, the air passes through the metal filters. Their mesh or baffle structure traps grease while the purified air continues on its path.
In labyrinth filters grease condenses on the metal surfaces and is trapped within the channels, preventing it from reaching the motor and reducing the risk of clogging.
This process not only improves air quality but also prevents grease buildup in the hood's ducts, which could pose a fire hazard or reduce the hood's efficiency.
Metal filters are considered reusable and, if properly maintained, can last a long time. Unlike charcoal filters, which need periodic replacement, metal filters don’t have an actual expiration date.
To ensure their longevity and efficiency, however, remember to perform regular maintenance: clean them every 1-2 months, depending on the hood’s usage. You can wash them by hand or in the dishwasher; in the latter case, a low-temperature cycle is recommended to avoid deformation.
If you don’t clean the filters regularly, a significant amount of grease can accumulate, posing a serious safety risk in the kitchen: not only will they fail to effectively extract air and vapors, but during cooking, heat can cause the trapped grease in the filters to melt and drip down. These droplets could contaminate the food below or, worse, cause a fire, especially when using gas cooktops.
Removing the hood filters without replacing them, thus leaving a “gap” between the hood’s core and the stovetop, severely compromises the appliance's functionality. The main consequences are:
For these same reasons, if a filter breaks, it’s essential to replace it, as a damaged filter cannot properly trap grease, leading to the previously mentioned consequences and causing irreversible damage to the hood’s motor.
If you’re unable to find a suitable metal filter for your hood, or if the manufacturer has gone out of business, there are several options you can consider:
If you need to replace metal filters because they are too worn, or if you want consultation on specific issues related to hood efficiency, Filtro Cappa is here for you!

Ho acquistato il filtro carbone della Faber ,originale, perfetto per la mia cucina. Nella confezione ce ne sono due, con un prezzo onesto. Nel sito hanno una grande varietà di prodotti per ogni esigenza. La spedizione è veloce e curata.
Ottimo servizio, ho ordinato i ricambi per una cappa FALMEC Plane 90, i ricambi arrivati sono ottimi ed originali , il servizio di spedizione è eccellente e velocissimo, il personale disponibile e molto cortese.
Esperienza eccellente. Bisogna inviare la foto dell’etichetta del prodotto e così i pezzi di ricambio esatti vengono verificati dal venditore. Risposta attenta e rapida. Risparmio garantito rispetto ai rivenditori fisici di zona: circa 30€ a pezzo nel mio caso. Consigliatissimo!
Consiglio vivamente, ho trovato sul sito il pezzo che mi serviva originale e a un prezzo minore rispetto ad altri siti, l'ordine è arrivato velocemente e ben impacchettato. Esperienza molto positiva
Ottimo servizio. P.S. Sono io che vi devo ringraziare, perché è molto raro trovare tanta serietà, professionalità e disponibilità, non ultimo il preoccuparsi anche dopo la consegna del parere del cliente. COMPLIMENTI.
Ciò che serviva a me non ce l'avevano in magazzino ma me lo hanno procurato comunque. È stato semplice e veloce. Inoltre non mi sono dovuto scervellare x capire quali delle mille mila versioni differenti serviva a me. Gli ho mandato una foto e hanno fatto tutto loro! Super professionali loro e super contento io!
Filtro Cappa mi ha assicurato che i filtri proposti andavano bene per la mia cappa ed infatti li ho acquistati e sono felicissimo; ottima assistenza e ottimo rapporto qualità/prezzo.
Prima esperienza di acquisto del filtro cappa metallico, ottima in facilità di ordine e tempi di consegna, non pensavo di trovare ancora il ricambio in quanto la cappa Faber ha 23 anni, sono estremamente soddisfatto, non escludo di acquistarne un altro da tenere di scorta quando torna disponibile sul sito
Ho trovato il filtro della mia vecchia cappa seguendo i consigli via chat che mi sono stati dati in quanto il vecchio modello non è più in produzione. La spedizione è stata velocissima e il filtro è perfetto. Grazie
Sostituzione motore ventola di aspirazione tutto ok. Il motore è arrivato imballato perfettamente confezionato onde evitare di essere sballottato e danneggiato. Montato sulla cappa airone angolare tutto ok. Rivenditore preciso e puntuale molto affidabile.
