An apparatus for filtering molten material, such as a molten metal-ceramic particle mixture, includes a porous cloth filter located so that the mixture must pass through the cloth filter, and a mechanical filter shaker that prevents the accumulation of filtered solids on the porous cloth filter. Where a further degree of filtration is required, there is a second filter located so that material leaving the porous cloth filter passes through the second filter after it passes through the porous cloth filter, and a mechanism that prevents an accumulation of filtered solids on the second filter. The second filter is desirably a porous media filter.
