This is a genuine Husqvarna air filter for petrol chainsaws, engineered to protect the engine by keeping dust and fines out of the intake. It suits popular models including the CS390 and CS2240 S II, with coverage across the 140/135/435/440 series. The element uses a rigid plastic frame with a fine white fleece/mesh media to balance high airflow with reliable filtration. Correct filtration helps maintain power, smooth idling, and easier starting while reducing cylinder and carburettor wear. As a Genuine Part (OEM No. 599 72 94 01), it is made to the original specification for fit and performance. The rectangular, low-profile design sits securely under the top cover and is straightforward to remove and refit during routine servicing.
