Overview

Keep your Husqvarna chainsaw performing smoothly with the Atunee 3-Pack Air Filter. Designed to fit a broad range of Husqvarna models, this set helps you simplify maintenance by providing three ready-to-install filters that are easy to swap in when cleaning your air intake.

The kit is a practical upgrade for routine maintenance and for when you want to keep your tools in peak, ready-to-work condition.
