A laundry machine adapted to dry laundry by means of a flow of drying air, comprising: a casing ; inside the casing, a laundry treating chamber adapted to contain the laundry to be dried; an air circuit in fluid communication with the laundry treating chamber through an inlet opening and through an outlet opening , and defining an air-path for the flow of drying air between said inlet and outlet openings; a filter housing for removably accommodating a de-fluff filter , said filter housing being provided in the air-path and being accessible through a housing aperture ; the de-fluff filter being arranged for trapping fluff or lint particles carried by the flow of drying air crossing said de-fluff filter , the de-fluff filter comprising a filtering element and a hollow chamber which comprises an inlet aperture and an outlet portion , wherein the filtering element is arranged on the outlet portion ; and the de-fluff filter further comprising an airflow diverter which is adapted to divide the hollow chamber of the de-fluff filter in a first portion and a second portion , characterized in that the airflow diverter comprises at least one filtering element for filtering the flow of drying air entering the first portion of the hollow chamber of the de-fluff filter thereby trapping fluff or lint particles, and the airflow diverter is adapted to divert the flow of drying air entering the de-fluff filter towards the first portion of the hollow chamber or towards the second portion of the hollow chamber according to an amount of fluff currently trapped in the at least one filtering element , wherein the airflow entering the hollow chamber of the de-fluff filter is progressively diverted from the first portion to the second portion as the flow rate through the at least one filtering element progressively drops due to accumulation of fluff at the least one filtering element . a casing ; inside the casing, a laundry treating chamber adapted to contain the laundry to be dried; an air circuit in fluid communication with the laundry treating chamber through an inlet opening and through an outlet opening , and defining an air-path for the flow of drying air between said inlet and outlet openings; a filter housing for removably accommodating a de-fluff filter , said filter housing being provided in the air-path and being accessible through a housing aperture ; the de-fluff filter being arranged for trapping fluff or lint particles carried by the flow of drying air crossing said de-fluff filter , the de-fluff filter comprising a filtering element and a hollow chamber which comprises an inlet aperture and an outlet portion , wherein the filtering element is arranged on the outlet portion ; and the de-fluff filter further comprising an airflow diverter which is adapted to divide the hollow chamber of the de-fluff filter in a first portion and a second portion , characterized in that the airflow diverter comprises at least one filtering element for filtering the flow of drying air entering the first portion of the hollow chamber of the de-fluff filter thereby trapping fluff or lint particles, and the airflow diverter is adapted to divert the flow of drying air entering the de-fluff filter towards the first portion of the hollow chamber or towards the second portion of the hollow chamber according to an amount of fluff currently trapped in the at least one filtering element , wherein the airflow entering the hollow chamber of the de-fluff filter is progressively diverted from the first portion to the second portion as the flow rate through the at least one filtering element progressively drops due to accumulation of fluff at the least one filtering element . <EOS>
