The Husqvarna 578120701 Air Filter is a genuine OEM replacement designed for the K950 and K1250 power cutters. As an OEM component, it is manufactured to Husqvarna's exact specifications, ensuring the correct fit and filtration performance for these high-demand cut-off saws. DHS Equipment supplies this part to help keep your equipment running at peak efficiency on the job.
Key Features
- OEM Filtration Specification — Manufactured to Husqvarna's exact filtration media and dimensional standards, delivering the same particulate capture efficiency as the original unit on your K950 or K1250.
- Direct Drop-In Replacement — Engineered to match the original air filter housing and seating profile, so installation follows the same service procedure as the factory component.
- Fits K950 and K1250 Power Cutters — Confirmed OEM fitment for both the K950 and K1250 handheld power cutters, covering common high-output saw configurations in the Husqvarna K-series lineup.
- Engine Protection Where It Counts — A clean, properly fitted air filter keeps abrasive dust and concrete particles out of the carburetor and combustion chamber, preserving engine compression and extending service intervals.
- Routine Service Compliance — Using the correct OEM part number this part ensures the filter meets the intake restriction and flow requirements specified in the Husqvarna service documentation for these models.
The air filter is the engine's first line of defense against the fine silica dust, concrete particles, and debris generated during cutting operations. It prevents abrasive material from entering the carburetor and cylinder, where even small amounts of contamination can accelerate wear on piston rings and cylinder walls. A clogged or deteriorated filter restricts airflow, causing rich running, loss of power, and potential overheating — replacing it on schedule with the correct OEM part maintains proper fuel-air mixture and protects the engine internals of your K950 or K1250 power cutter.
