Craftsman String Trimmer Filter Parts

Craftsman String Trimmer Air Filter Parts

Your Craftsman string trimmer engine needs clean air to run smoothly. A clogged or missing air filter forces the engine to work harder, burns more fuel, and runs rough. If your trimmer won't start, surges during use, or stalls under load, a dirty air filter is often the culprit.

Foam and paper filters both need regular seasonal maintenance — especially if you're using your trimmer in dusty conditions. Replace or clean your filter before each mowing season, and swap in a fresh one mid-season if you're a heavy user. Repair Clinic stocks genuine Craftsman air filter assemblies and filter elements for all major trimmer models.

• Trimmer won't start or starts hard: Clogged air filter blocking fuel-air mixture
• Engine surges or loses power: Restricted airflow forces lean running condition
• Excessive smoke from muffler: Engine running rich due to air restriction
• Poor fuel economy: Engine compensating for restricted intake
• Visible dirt or debris on filter: Time for cleaning or replacement

Find your Craftsman trimmer model number on the engine block or equipment label, then enter it into the Craftsman String Trimmer Filter Parts search to see the correct air filter assembly for your specific model.

Craftsman String Trimmer Air Filter FAQs

What's the difference between foam and paper air filters on Craftsman trimmers?

Craftsman trimmers use either foam or paper filter elements depending on the model and engine type. Foam filters are washable and reusable — clean them with soap and water, let them dry completely, then reinstall. Paper filters are disposable and should be replaced when dirty (they can't be cleaned effectively). Always match the filter type and size to your trimmer model — swapping one for the other can affect engine performance and fuel consumption. Check your owner's manual or enter your model number to confirm which type yours uses.

How often should I replace my Craftsman string trimmer air filter?

Replace your air filter every season before you start trimming, and mid-season if you're doing heavy work in dusty conditions. A heavily used trimmer in sandy or dry grass may need a filter swap every 50 hours of operation. If you store your trimmer over winter with a dirty filter, ethanol in the old fuel can gum up the carburetor — a fresh, clean filter helps prevent that. Visual inspection is your best guide: if the filter looks dark or clogged, it's time for a change.

Can I use a universal aftermarket air filter instead of a Craftsman OEM filter?

You can try a universal aftermarket filter, but OEM Craftsman filters are engineered for your specific engine's airflow and fuel mixture. An improperly sized filter (too restrictive or too loose) can cause the engine to run lean, which stalls the trimmer under load, or rich, which produces excessive smoke. Aftermarket filters also fit less consistently in the housing, allowing unfiltered air to bypass the element. For reliable cold starts and consistent power, stick with the genuine Craftsman filter assembly for your model.

My Craftsman trimmer runs fine but the air filter housing is cracked. Do I need to replace the whole assembly?

If the housing is cracked, replacing just the filter element won't solve the problem — unfiltered air will enter the engine around the crack. You'll need the complete air filter assembly (housing + element) to seal properly and protect your engine. A cracked housing also indicates impact damage; check the rest of the trimmer for bent fuel lines or carburetor damage. Enter your Craftsman trimmer model number to find the correct air filter assembly, which includes both the housing and the filter element.

Craftsman String Trimmer Model Number: Where to Look

On most Craftsman string trimmers, the model number is printed on an equipment label near the engine or on the main housing. Check around the powerhead, handle, and engine block for a tag or sticker, and clean off dirt if the numbers are hard to read. Once you have it, enter the number in the model search to pull up parts matched to your entire trimmer, not just the filter system. The catalog will narrow to parts made for your specific Craftsman model, including maintenance and replacement parts. Using the model number saves time, prevents mix-ups between similar trimmers, and helps you order with confidence knowing the fit is right.
