1. A filter for treating a fluid in a piping of a heating and/or cooling system, said filter comprising:
a main body internally comprising at least one chamber,
a first mouth and a second mouth respectively comprising a first duct and a second duct allowing a fluid to enter or exit said at least one chamber, wherein said first mouth has a first longitudinal axis and the second mouth has a second longitudinal axis, the second mouth being positioned on the main body in such a way that its second longitudinal axis is substantially perpendicular to the first longitudinal axis of the first mouth;
a first filtering element for treating the fluid, housed at least partially in said at least one chamber, said first filtering element comprising at least one magnetic element adapted to intercept and trap ferrous impurities that are present in the fluid to be treated; and
a shut-off element housed in a portion of said at least one chamber communicating with said first duct and said second duct, wherein said shut-off element has a substantially cylindrical or truncated conical shape and is provided with an outer wall, a first channel, a second channel, and a septum adapted to divide the first channel and the second channel from each other, said shut-off element being adapted to rotate about a longitudinal axis of its own, which is substantially parallel to or coincides with the first longitudinal axis of the first mouth, so that the shut-off element can be reversibly switched between:
a first position, in which said shut-off element is positioned to allow a flow of the fluid to enter said at least one chamber or exit said at least one chamber both via a communication of the first duct with said at least one chamber through the first channel and via a communication of the second duct with said at least one chamber through the second channel, and
a second position, in which said shut-off element is positioned to prevent the flow of the fluid from entering said at least one chamber or exiting said at least one chamber, said outer wall obstructing both the communication of the first duct with said at least one chamber through the first channel and the communication of the second duct with said at least one chamber through the second channel.
