How to Clean a DPF Filter Yourself and How Much It Costs?

Are you experiencing reduced performance and increased fuel consumption in your diesel vehicle? Chances are, your Diesel Particulate Filter (DPF) may be clogged. A clogged DPF can lead to various issues, including engine damage and costly repairs. Before rushing to the nearest mechanic and emptying your wallet, it’s worth considering that cleaning a DPF filter yourself is entirely possible. This article will guide you through How to Clean a DPF Filter Yourself, saving you time and money.

How to Clean a DPF Filter Yourself?

Here are the best three methods we will discuss:

1-Cleaning the DPF Filter with the Active Regeneration

The burning of exhaust soot, also known as active regeneration, is a crucial process in maintaining the efficiency and cleanliness of a vehicle’s DPF filter. Regeneration can occur in two ways: passive regeneration and active regeneration. If passive regeneration fails to activate, the exhaust will accumulate with soot. It often happens when short and frequent trips are made, preventing the engine from reaching optimal operating temperatures. To initiate passive regeneration, driving on the highway for at least 30 minutes at a consistent speed is recommended.

Active regeneration should be employed if passive regeneration does not work effectively. Active regeneration is a straightforward and cost-free method to clean the DPF filter. To carry out this process successfully, drivers should maintain a constant speed of 30 to 40 mph @ 2300 rpm on a highway or traffic-free road.

2-Cleaning the DPF with additives

Cleaning the DPF (Diesel Particulate Filter) with additives is an effective and affordable way to maintain a clean and efficient exhaust system. You can effectively remove ash and soot from the filter using premium-quality additives, which can be easily purchased at your local mechanical store or online for less than $35. The process is simple: after buying the additive, pour it into your vehicle’s fuel tank according to the instruction chart provided on the additive bottle. It is crucial to follow these instructions carefully for the additive to work correctly.

Once you have filled your fuel tank with the additive, start your vehicle and drive for approximately 20 to 30 minutes. It will allow the additive to mix with the exhaust soot and effectively clean the DPF.

3-Cleaning the DPF Filter with Compressed Air-Pressure

When cleaning your vehicle with compressed air pressure, you’ll need a few additional tools and some precautions you must take. If you need more confidence in your abilities, it’s best to leave this task to professionals with the necessary tools and expertise. While high-pressure airflow can effectively remove loose ash from your vehicle, it won’t be as effective against stubborn soot particles. In such cases, your mechanic may suggest pressure washing the DPF filter.

I recommend opting for low-pressure washing instead of high-pressure washing. High-pressure washing, with its immense power of around 2,000 psi or 140 bars, can cause severe damage to your Engine filter. It is because the DPF block is typically only about 2

How Much Does It Cost to Have a DPF Filter Cleaned?

The cost of having a DPF filter cleaned varies depending on the type of blockage. You can generally expect to pay anywhere from $50 to $100 for normal soot and ash cleaning. If you prefer to hire a mechanic for the cleaning process, the cost typically ranges between $300 and $700. In comparison, these cleaning methods are significantly cheaper than replacing a DPF filter altogether.


Cleaning a DPF filter yourself is a cost-effective and practical solution to maintain the performance and efficiency of your diesel vehicle. Following the step-by-step process outlined in the article, How to Clean a DPF Filter Yourself, you can effectively remove soot and other pollutants from your filter, ensuring its longevity and preventing any potential damage to your engine. Remember to exercise caution and wear protective gear during the cleaning process.
Regular maintenance of your DPF filter will save you money on costly repairs and contribute to a cleaner environment by reducing harmful emissions. So why wait? Take charge of your vehicle’s health today and give your DPF filter the care it deserves.


Can I Clean My DPF Myself?

Yes, cleaning your DPF (Diesel Particulate Filter) is possible, but it can be a complex and time-consuming process. The DPF collects soot and other particulate matter from the exhaust gases of a diesel engine, and over time it can become clogged, leading to reduced performance and increased emissions. To clean the DPF yourself, you must follow specific instructions from the manufacturer or consult a reliable guide. Generally, this involves removing the filter from the vehicle and using a specialized cleaning solution or high-pressure water to remove the built-up soot. 

How Do I Manually Clean My DPF?

To manually clean your diesel particulate filter (DPF), you will need to follow a few steps. Ensure the engine is excellent and the vehicle is parked in a well-ventilated area. Then, locate the DPF under the car, usually near the exhaust system. Remove the DPF from its mounting brackets carefully. Use a specialized cleaning solution or a mixture of warm water and dish soap to soak the filter for about 30 minutes. Gently scrub it with a soft brush to remove any built-up soot or debris.

How Do You Clear a Blocked DPF Filter?

Clearing a blocked DPF (Diesel Particulate Filter) filter can be tricky, but you can try a few methods. One standard practice is to perform a forced regeneration. It involves driving the vehicle at high speeds for an extended period, typically on the highway or open road. The increased exhaust temperature during this drive helps to burn off the accumulated soot and clear the blockage in the filter.Another option is to use a DPF cleaning additive. These additives are designed to break down and remove the soot particles causing the blockage. Depending on the specific product instructions, they can be added directly to your fuel tank or mixed with engine oil.

Can I Pressure Wash My DPF Filter?

Yes, but pressure washing is not recommended.Because high pressure damages your DPF filter, and the filter may crack as a result.
