Cooker hoods are ducted, and only need grease filters to vent them, removing cooking fumes and odors.

A ductless hood recirculates cooker hoods and pushes air through a charcoal filter. Because of this hood, they can restore the kitchen by removing all cooking fumes and odors before cleaning.

Generally, charcoal filters are not replaced as often as grease filters. But some manufacturing companies recommend that you change the carbon filter at least once every three months.

But some of them will need to change less frequently in six to nine months.

You should wash the filter every four to eight weeks to prevent grease buildup.

Now coming to the second type of filter carbon filter, paper filter or fabric grease filter which cannot be cleaned.
