Description
xCleaner cabin air for demanding Duramax drives
Doc's Diesel Cabin Air Filters are built to remove dust, pollen, and other airborne particles from the interior, helping create a fresher cabin environment on long trips or daily commutes in Chevy/GMC Duramax trucks. These filters are designed for a precise fit and are among the easiest to replace, with the typical location behind the glove box. When installed following the manufacturer’s guidelines, the filter will not affect your vehicle’s warranty.
Key fit and interchange
- Fitment: Chevrolet/GMC 6.6L Duramax 2500HD and 3500HD (2020–2025) and Chevrolet/GMC 3.0L Duramax (2020+).
- Interchange: Replaces GM 13508023 and other common part numbers (CF185, CF1184C, PA10369, PC4211C, TC3822AC).
- Third-party tested: the electrostatic media stops particles down to 0.001 microns in filtration assessments.
What to expect in real-world use
- In dusty rural roads or heavy city traffic, you may notice a noticeable reduction in dust on dashboards and in air intake quality during circulation.
- On longer drives, you might experience steadier airflow and a clearer climate inside the cabin, especially when the AC is in use.
- The filter’s electrostatic media is designed to balance particle capture with preserved airflow for consistent performance.
Maintenance guidance
- Replacement guidelines: typically every 15,000 miles or 12 months, depending on driving conditions and vehicle usage.
- Follow your vehicle’s warranty requirements and ensure proper installation to avoid issues.
- Keep an eye on the cabin environment; if you notice more dust or pollen, consider replacing sooner.
