How to Start Cleaning DPF Filters?


Are you a vehicle owner concerned about your diesel particulate filter (DPF) and its maintenance? You’re not alone! Cleaning DPF is an essential task for all diesel vehicle owners, and it can help your vehicle run more efficiently and effectively. In this article, we’ll dive into what DPF is, why it needs cleaning, and the various methods for cleaning it.

What is DPF?

Diesel Particulate Filter, or DPF, is a device installed in the exhaust system of diesel engines to reduce emissions. It works by capturing and storing soot particles produced during combustion. Over time, the filter becomes saturated, and it must be cleaned to maintain its efficiency and prevent potential engine problems. Learn more about DPF from the U.S. Environmental Protection Agency (EPA).

Why Clean DPF?

Reduce Emissions

Cleaning your DPF ensures that it continues to function properly in capturing particles. This results in lower emissions, which is beneficial for the environment and helps your vehicle meet emission standards.

Extend DPF Lifespan

Regular cleaning can extend the life of your DPF. A clogged filter can cause increased backpressure in the exhaust system, potentially leading to filter damage or even engine issues.

Improve Engine Performance

A clean DPF allows for better airflow in the exhaust system. This improves engine performance by reducing backpressure and providing optimal conditions for efficient combustion.

What your Diesel Particulate Filter could look like!

Yikes! You may not realize it but your filter could look the same way. Even if you do not drive the vehicle for many miles just having the car on and idle will cause a mass build up of soot. This a prime example of a filter that is rejected by the dealership. After our cleaning process the filter was good as new and the truck back on the road. If your filter contains DEF inside of it that is no issue for us. DEF soaked filters must be cleaned thoroughly through means besides baking. The DEF inside of the ceramic can solidify due to a chemical reaction and actually become a cement like substance making your filter need immediate replacement.

DPF Cleaning

Manual Cleaning

Ash Removal

This process involves physically removing the DPF from your vehicle and using compressed air or a vacuum to remove ash buildup from the filter. It’s essential to exercise caution during this process, as damage to the filter can occur if not handled correctly.

Filter Regeneration

Filter regeneration is the process of burning off accumulated soot in the DPF. This can be done passively (while driving) or actively (by initiating a regeneration cycle with a diagnostic tool). Be aware that excessive regeneration can shorten the lifespan of the filter. For more information, check out this article on DPF regeneration.

Professional Cleaning

Ultrasonic Cleaning

Ultrasonic cleaning involves submerging the DPF in a cleaning solution and using high-frequency sound waves to remove ash and soot. This method is highly effective and is usually performed by professionals at specialized service centers.

Chemical Cleaning

Chemical cleaning utilizes specific chemicals to dissolve soot and ash trapped in the DPF. It often requires soaking the filter for an extended period, followed by thorough rinsing. This method should be done by professionals, as improper handling can damage the filter.

On-Board DPF Cleaning

Some vehicles come equipped with on-board DPF cleaning systems. These systems initiate automatic regeneration cycles to burn off soot while driving, without the need for manual intervention. Keep in mind that on-board cleaning may not be sufficient for heavily clogged filters, and manual or professional cleaning might still be necessary.

Cleaning Tips

Preventive Maintenance

Performing preventive maintenance on your vehicle, such as regular oil changes and servicing, can help prolong the life of your DPF. This also includes using high-quality fuel and adhering to the manufacturer’s recommended maintenance schedule.

Monitor Warning Signs

Keep an eye on your vehicle’s warning lights and messages related to the DPF. Addressing issues early can prevent more significant problems down the road.

Choose the Right Cleaning Method

Evaluate the condition of your DPF and choose the most suitable cleaning method. While manual cleaning might be sufficient for mild cases, professional cleaning methods such as ultrasonic or chemical cleaning may be necessary for heavily clogged filters.

Choose the Right DPF Cleaner

Maintaining a clean DPF is crucial for the health of your diesel engine and the environment. Regular cleaning can help reduce emissions, extend the DPF lifespan, and improve engine performance. By following preventive maintenance practices, monitoring warning signs, and choosing the right cleaning method, you can ensure that your DPF remains in top condition.

  1. How often should I clean my DPF? The frequency of DPF cleaning depends on various factors, such as driving conditions, vehicle usage, and the type of engine. Generally, it is recommended to clean the DPF every 30,000 to 50,000 miles. Consult your vehicle’s owner’s manual for specific recommendations.
  2. Can I clean my DPF myself? While some manual cleaning methods can be performed by vehicle owners, it’s crucial to exercise caution and follow proper procedures. If you’re unsure, it’s best to seek professional assistance.
  3. What are the symptoms of a clogged DPF? Some common symptoms of a clogged DPF include reduced engine performance, poor fuel economy, increased emissions, and warning lights or messages related to the DPF system.
  4. Will removing my DPF improve my vehicle’s performance? Removing a DPF can cause your vehicle to fail emissions tests, and it’s illegal in many regions. Instead of removing the DPF, focus on proper maintenance and cleaning to maintain engine performance.
  5. Can driving habits affect my DPF’s lifespan? Yes, driving habits can significantly impact the lifespan and performance of your DPF. Frequent short trips, stop-and-go traffic, and low-speed driving can contribute to DPF clogging. Adopting more fuel-efficient driving habits and longer trips can help reduce DPF-related issues.
