There is provided a dual stage ceramic foam molten metal filtration system and method. Coarse and fine filters are mounted adjacent to one another in a molten metal flow path. A convection preheat apparatus provides preheat for both filters. A vent structure is included to vent air which may be trapped in a gap which is formed between the two filters.
