Carbon filter for kitchen hood fan
whaleross@kbin.social to 
My kitchen stove hood fan needs a new carbon filter as the current one lookes pretty caked with grease from the previous owners of the place. It turns out the manufacturers filters cost €150 which I find a bit excessive. Filters seem to be the printer ink of the kitchen.
So I'm thinking either if it is possible to clean out the current one, or reuse the casing and refill it with some bulk carbon filter material, if there is such to be found.
I have no idea, I've never done anything of this sort before.
Experiences, ideas, suggestions much appreciated.
Edit: There is a metal mesh under that is washable, but also an internal filter, as the hood is recirculating the air back into the kitchen. My apartment building does not allow kitchen fan exhaust into the ventilation system.
Are you sure it’s a carbon filter? You can try washing it to get the grease out, most of the kitchen filters I’ve seen aren’t carbon but instead a mesh weave of metal. You can likely find a carbon filter that would work online, or something bigger and cut it down to size.

There is a steel mesh under that is washable and a carbon filter inside. It's a recirculating system so exhaust is back into the kitchen.
Extractor hoods have mesh or metal filters, but recirculating hoods have an additional charcoal filter to remove odor, because they blow the air back into the room.
