A filter for molten metal comprises a series of at least two refractory mineral material plates which define between them one or more cavities. The plates each comprise a series of holes through which the liquid metal passes and by which the liquid metal is filtered. At least one of the cavities contains a material for treating the metal, for example a material for inoculating the liquid metal. The filter is used among other things to filter and treat molten metals simultaneously and to improve the quality of the metal.
