For a more thorough clean, use compressed air to blow out any remaining debris. Hold the air filter at a distance to avoid damaging the material.

7. Reinstall the Air Filter

Once the filter is clean and dry, place it back in the housing in the correct orientation. Secure the housing with screws or clips.
