How Do You Clean an Air Compressor Filter?

Published in Air Compressor Maintenance 3 mins read

The referenced video suggests cleaning your air compressor filter once a month until it's damaged, at which point you'll need to replace it. The general steps would likely involve removing the old filter, cleaning or replacing it with a new, clean filter, and then reinstalling the cap. More detail would be required depending on the specific type of air compressor.

Since the video excerpt doesn't provide detailed steps, here's a general guideline for cleaning air compressor filters:

  1. Consult Your Manual: Always refer to your air compressor's manual for specific instructions, as filter types and cleaning procedures can vary.

  2. Safety First: Disconnect the air compressor from the power source to prevent accidental startup. Depressurize the tank completely.

  3. Locate the Filter: The air filter is usually located at the air intake. It's often housed in a plastic or metal cover.

  4. Remove the Filter Cover: Unscrew or unclip the cover to access the filter.

  5. Remove the Filter: Carefully take out the air filter. Note its orientation for proper reinstallation.

  6. Cleaning Options:

    • For Foam Filters: Wash the foam filter with warm, soapy water. Gently squeeze out the excess water, and let it air dry completely before reinstalling.
    • For Paper or Cartridge Filters: Gently tap the filter against a solid surface to dislodge loose dirt and debris. You can also use compressed air (at low pressure) to blow out the filter from the inside out. Do not wash paper filters.
    • Inspect for Damage: Check the filter for tears, holes, or excessive dirt buildup that cannot be removed. If damaged, replace the filter.
  7. Reinstall the Filter: Place the clean or new filter back in its housing, ensuring it's oriented correctly.

  8. Reattach the Filter Cover: Secure the cover back in place.

  9. Test the Compressor: Reconnect the air compressor to the power source and turn it on. Listen for any unusual noises or performance issues.

Important Considerations:

  • Cleaning Frequency: Check your air compressor's manual for recommended cleaning intervals. If you use your compressor frequently or in dusty environments, you may need to clean the filter more often.
  • Filter Replacement: Air filters have a limited lifespan. Even with regular cleaning, they will eventually need to be replaced. Refer to your manual for replacement recommendations.
  • Alternative Cleaning Solutions: While soapy water is generally safe for foam filters, avoid using harsh chemicals or solvents that could damage the filter material.
