Husqvarna Lawn Mower Air Filter 579 27 93-01 | eBay 
A clean air filter is essential for maintaining optimal performance in your Husqvarna push mower. Just like your car engine needs clean air for efficient combustion, your mower's engine relies on a fresh air filter to prevent dirt, dust, and debris from entering the system. A clogged air filter can restrict airflow, hinder engine performance, and even lead to engine damage.

This guide will walk you through the simple process of replacing the air filter on your Husqvarna push mower. Remember, before performing any maintenance on your mower, always consult your owner's manual for specific instructions related to your model.

What You'll Need:

  • Replacement air filter (refer to your owner's manual for the correct part number)
  • A clean work surface
  • A shop rag (optional)


  1. Safety First: Disconnect the spark plug wire from the spark plug to prevent the engine from accidentally starting.

  2. Locate the Air Filter: The air filter housing is typically located near the top of the engine, often on the side or towards the front. It will usually be made of plastic and may have clips or latches to secure it.

  3. Remove the Air Filter Housing: Consult your owner's manual for specific instructions on how to detach the air filter housing. It may involve squeezing clips or releasing latches.

  4. Inspect the Old Air Filter: Carefully remove the old air filter. Take a moment to inspect it for any signs of damage or excessive dirt buildup. If the filter is torn or heavily clogged, replacing it is a must. A slightly dirty paper filter can sometimes be cleaned with a compressed air hose (from the outside in), but a heavily soiled filter or a foam filter should always be replaced.

  5. Install the New Air Filter: Take your new air filter and ensure it matches the old one in size and shape. Carefully insert the new filter into the housing, making sure it sits flush and secure.

  6. Reattach the Air Filter Housing: Secure the air filter housing back onto the engine compartment, following the same procedure you used to detach it (snapping latches or securing clips).

  7. Reconnect the Spark Plug Wire: Reconnect the spark plug wire back onto the spark plug. Double-check that the connection is secure.

Congratulations! You've successfully replaced the air filter on your Husqvarna push mower.

Additional Tips:

  • How often you need to replace the air filter will depend on how often you use your mower and the mowing conditions. A good rule of thumb is to check the filter after every 25 hours of operation or at the beginning of each mowing season.
  • Remember to dispose of the old air filter properly. Do not burn it, as this can release harmful fumes.

By following these simple steps and consulting your owner's manual, you can keep your Husqvarna push mower running smoothly and efficiently for years to come.
