Fume extraction apparatus and assembly

A fume extraction and filter apparatus, comprising:

• a housing including a base and a top portion connected to a top side of the base, the base including an inlet in a side thereof, the inlet leading into the housing and in flow communication with an outlet in the top portion;
• a motor disposed in the housing;
• a blower assembly disposed in the housing and drivable by the motor to draw air into the inlet and cause the air to exit through the outlet;
• a filter disposed in the housing between the inlet and the outlet and arranged to filter air drawn in the inlet before the air exits through the outlet, wherein the blower assembly is a double-stage blower including an intake impeller and an output impeller, the intake impeller being closer to the inlet than the output impeller and the output impeller being closer to the outlet than the intake impeller.
