Embodiments of present disclosure relates to a filter for use in a vacuum food processor and a vacuum food processor including the filter. The filter comprising: a first filter part adapted to direct a suction airflow generated by a vacuum module of the vacuum food processor into the filter via an inlet channel; and a second filter part adapted to coaxially fit with the first filter part and comprising a cavity, the cavity adapted to maintain non-gaseous substance that is moving along with the suction airflow inside the filter, wherein the first filter part and the second filter part jointly define an outlet channel at a bottom of first filter part, the outlet channel adapted to direct the suction airflow outside the filter. In this way, the food particles/bubbles can be prevented from entering the vacuum module, while the suction airflow is allowed to freely flow to the vacuum module.
