MVHR Grease Filter?

[MJNewton]

Does anyone know of grease filter that I could put inside my kitchen MVHR extract vent? Ideally one that would sit inside the 125mm duct so I can keep the current terminal.

 

Rather than bespoke item I wondered if I could just use some generic filter media of some sort, cut to a round shape and shoved up inside?

Carbon pond filter media ..?  Cheap and washable.

Would that be good for grease? I was under the impression carbon has really small pathways hence why it's good for trapping smells?

I mean this stuff - Filter foam

[MJNewton]

Ah, yes, okay - will take a look.

 

Found this stuff which might work too described as a cut-to-size washable mesh filter (for extractor hoods):

I think what you are after is a G3 filter. Search for that and it give you plenty of cheap options you can cut

Great, thanks everyone!
