a support having a suction opening, a top surface, a bottom surface, and a connecting edge between the top surface and the bottom surface, wherein the connecting edge has a front surface and a rear surface opposite to the front surface;

one or more heating elements arranged on the support in proximity to the top surface; and

suction means connected in fluid communication with the suction opening and configured to draw in cooking fumes, in proximity to the heating elements, wherein the suction means comprises first and second filters;

wherein the first filter has a first seat and comprises a first filter element in the first seat, wherein the first seat is accessible through the suction opening to allow extraction and/or insertion of the first filter element,

wherein the second filter, located downstream from the first filter, has a second seat, separate from the first seat, and comprises a plurality of second filter elements of different types with respect to the first filter element and inserted in the second seat,

wherein the second seat is located at the rear surface of the connecting edge and the first seat is interposed between the suction opening and the second seat, and

wherein the second seat is accessible through the first seat, to allow extraction and/or insertion of the second filter elements through the suction opening, passing through the first seat.

2. The cooktop of claim 1 , further comprising:

an exhaust duct located downstream from the suction means at the rear surface;

wherein the second seat is formed in the exhaust duct, and

wherein the exhaust duct has a peripheral wall separating the first seat from the second seat.

3. The cooktop of claim 2 , wherein the second seat has a pull-out opening facing the first seat, and

wherein the pull-out opening being is, defined on the peripheral wall.

4. The cooktop of claim 3 , further comprising:

a door associated with the pull-out opening and configured to slide toward and/or away from the support to open and/or close the pull-out opening.

5. The cooktop of claim 3 , wherein the first seat has a passage opening facing the pull-out opening to allow passage of the second filter elements.

6. The cooktop of claim 5 , further comprising:

a suction duct in fluid communication with an outside environment through the suction opening;

wherein the first seat is at least partially defined by the suction duct,

wherein the suction duct comprises a side wall located at the first seat and projecting from a bottom surface of the support, and,

wherein the passage opening is formed in the side wall.

7. The cooktop of claim 5 , wherein the first seat comprises a cover element associated with the passage opening, to open and/or close the passage opening.

8. The cooktop of claim 7 , wherein the cover element is hinged to the side wall at the passage opening to open toward an interior of the first seat.

9. The cooktop of claim 3 , further comprising:

extraction means to extract the second filter elements, configured to move the second filter elements into an area in front of the pull-out opening for a user to be able to pull out the second filter elements.

10. The cooktop of claim 9 , wherein the extraction means are at least partially inserted in the second seat.
