Air Filter Kit for Husqvarna 445 and 450 Chainsaws

This replacement air filter kit fits Husqvarna 445, 450, 450 Rancher, 450 e II and 445E II chainsaws. It replaces original part numbers 531309681 and 544080803. The kit includes two air filters for petrol-powered saws. Owners of other chainsaw models or electric units should look elsewhere.

Sustained filtration during extended cutting

The filters maintain airflow while trapping dust and debris during prolonged operation in dusty conditions. Consistent filtration helps the engine run steadily over long work periods without power loss from a clogged intake. Regular replacement supports reliable performance across repeated heavy use.

Low restriction design for normal petrol saw

Clean filters allow the engine to breathe freely, reducing strain and keeping exhaust temperatures in check during typical cutting tasks. Unrestricted intake contributes to smoother running and lower noise from the motor struggling for air. The petrol engine maintains its expected fuel efficiency when the filters are fresh.

Questions about this item

Will the air filter kit keep my 450 Rancher running cleanly during all-day cutting?

The replacement filters match part numbers 531309681 and 544080803, so they seal the carburettor intake on your 450 Rancher and maintain steady airflow through long work sessions.

Do I need any extra parts or tools to fit these filters on my 445E II?

No extra parts are required; the kit contains two direct-fit air filters that install into the existing filter housing on the 445E II using the standard clips.

Can I use this kit on an older 445 that still has the original filter housing?

Yes, the filters replace part numbers 531309681 and 544080803, which are specified for the 445 as well as the newer 450 e II and 450 Rancher models.
