Cabin air filters should be cleaned after every 250 hrs. or even earlier if required. During every service the cabin air filters should be cleaned. Even after this if the filter is found choked or damaged, replace it with a new one. Do not use dirty or damaged filter as the impure air may severely reduce the cooling effect.
