Diesel particulate filters are components in engines that trap and remove diesel particles from the exhaust.
DPFs are an essential piece of equipment for any truck that spends time on the road. These filters help trap particulate matter, preventing it from entering the atmosphere and causing pollution.
Finding the correct diesel emissions component on the internet may seem difficult. Often you believe you’ve found the right part until it turns out that it doesn’t fit! Alternatively, you discover a website that sells parts for your vehicle, but they don’t stock your model.
There are aftermarket parts, OEMs, and everything in between. Even for experienced Fleet Managers, obtaining the greatest bargains and correct components might be difficult. Not to mention owner-operators who may not understand industry jargon or even what search phrases to use.

What is a DPF?
A DPF is a device that captures and filters out delicate particulate matter from the exhaust of diesel engines. They were first introduced in the US in 2007, and since then, they have become standard equipment on all new diesel trucks.
DPFs are designed to remove particulate matter (PM) from exhaust gas before it has a chance to exit the tailpipe. Particulate matter is made up of a variety of solid and liquid particles emitted from diesel fuel combustion.
These particulates can include soot, metallic ash, sulfates, and organic compounds. Inhaling particulate matter can have serious health consequences, so it’s essential to remove it from engine exhaust before it has a chance to enter the atmosphere.
How Does a DPF Work?
DPFs trap particulate matter in the exhaust and hold it until it can be burned off. The filter comprises a ceramic or metallic honeycomb-like structure with tiny pores.
As exhaust gas flows through the filter, the particulate matter is caught on the surface of the pores. Over time, the filter will become clogged with particulate matter and need to be cleaned or replaced.
Cleaning a DPF can be done using a process called regeneration. Regeneration is when the DPF burns off the trapped particulate matter, cleaning the filter and restoring it to its original condition.
There are two types of regeneration for DPFs: passive and active. Passive regeneration happens automatically as the engine is running and does not require any intervention from the driver.
Active regeneration requires the driver to take action, usually injecting additional fuel into the exhaust stream or manually operating a switch inside the cab.
Most DPFs will have some sensor that will monitor the level of particulate matter in the filter and notify the driver when it’s time to clean it.
Tips For Picking An DPF Filter
Now that we know what a DPF is and how it works, let’s take a look at some tips for choosing the right one for your truck.
1. Know Your Engine
The first step in choosing a DPF is to know which engine you have. There are many different engines on the market, and each one requires a specific DPF.
Knowing your engine make and model is the best way to ensure you’re getting the right part for your truck. You can find this information in your truck’s owner’s manual or the engine itself.
2. Consider Your Driving habits
Your driving habits will significantly impact which DPF is right for your truck. If you do a lot of stop-and-go driving, you’ll need a filter that can handle higher levels of particulate matter.
If you do mostly highway driving, you’ll need a filter that can withstand prolonged periods of use. Consider how and where you drive when choosing a DPF.
3. Choose the Right Size
DPFs come in various sizes, so it’s essential to choose one that’s the right size for your truck. If you have a large truck with many horsepowers, you’ll need a bigger DPF.
Conversely, if you have a smaller truck, you can get away with a smaller filter. Choosing the right size DPF will help ensure your engine performs at its best.
4. Consider Your Budget
DPFs can range in price, so it’s essential to consider your budget when choosing a filter. If you’re looking for a high-quality filter, you’ll need to be prepared to spend more money.
However, plenty of good-quality DPFs on the market won’t break the bank. You can find great deals from sellers like DPF Parts Direct. Consider your budget and decide how much you’re willing to spend on a DPF before beginning your search.
5. Read Online Reviews
One of the best ways to find a good quality DPF is to read online reviews. Many websites allow customers to leave reviews of products they’ve purchased, so you can know which filters are good and which ones to avoid.
Reading reviews will also give you an idea of what other customers look for in a DPF to make sure you’re getting a filter that meets your needs.
When it’s time to replace your truck’s DPF, there are a few things you need to keep in mind. Choosing the right filter is essential to running your engine smoothly and avoiding costly repairs. Use this guide to help you choose the best DPF for your truck.
