Nardi 03-200305 Cooker and Oven Spares and Parts

A good size and simple to fit. All you need is a good pair of scissors to cut to size.
A little tip Surgical Spirits or rubbing alcohol is brilliant at removing the grease that has hardened on the filter frame. Paint on with a fine brush and wipe off with kitchen towel. Obviously Surgical Spirits and Rubbing Alcohol are extremely flammable, use with good ventilation and no flames, sources of ignition. Do not even switch the fan on as an electrical spark could cause an explosion. It does not actually say in the instructions but I would fit the foam filter first with the black carbon filter second. That way the grease is trapped before getting to the Carbon filter.
