Exhaust Filter - What are the benefits and when it should be changed?

An exhaust filter is a mechanical component that removes pollutants from a vehicle's exhaust system. The material used to construct an exhaust filter varies depending on the type. For instance, a household exhaust filter may be made of fiberglass, electrostatic carbon, or polyester filter media pads. These are then placed in a frame and inserted into the vehicle's ductwork. Industrial exhaust filters are more complex and often feature additional filtration methods.

An exhaust filter helps improve fuel economy by collecting vaporized oil and other liquids from air venting from gasoline engines and vacuum pumps. Raw exhaust should never be vented indoors or outdoors because it contains fumes and smoke that harm people and the environment. These filters are also crucial for improving pump efficiency by conserving lubricating oil. Broken seals in a pump can allow oil to atomize. This vaporized oil harms the air and can enter employees' lungs.

An exhaust filter has two parts: a first filter member with a hollow body that extends between a first screen and a flow diverter and a second filter member having an open, movable sidewall. The filter's design allows it to be adjusted to fit a vehicle's exhaust system.

How to clean an exhaust filter?

There are a few simple cleaning solutions available. First, you can use a steam cleaner. Just place your dirty filter over a towel, and the steam cleaner will remove the grease. Then, you can use anti-grease dishwashing soap and a thick bristled brush to scrub off the remaining dirt. Once you've removed the residue, you can wipe it with a microfiber cloth.

Generally, it's best to clean your exhaust filter at least once a month. This will help keep it working efficiently and keep your car running well. Once you've cleaned the filter, it may take up to 24 hours to dry. If you're concerned about the health of your vehicle's engine, cleaning your exhaust filter is vital. It improves the airflow and boosts your car's engine performance.

Passive regeneration is another method for cleaning your exhaust filter. This involves raising the temperature of the exhaust to allow the particulate matter to burn off. This is an effective and efficient method to remove PM, but it requires a higher temperature. Passive regeneration is a natural cleaning process.

When should I change my exhaust filter?

A dirty exhaust filter can cause the engine to stall or even damage the engine. To avoid this, you should replace the filter as soon as the oil light comes on. If you wait too long, the engine may enter limp mode, which is unsafe even at low speeds. Then, soot will accumulate until the oil filter needs to be replaced. To avoid this, you can change the filter to save money and time. If this is the first time you have performed this task, take a picture of the process so you can recall how to replace it the next time.

The diesel particulate filter (DPF) is a ceramic filter inside the exhaust system. It captures the soot and ash released from the engine and is harmful to the environment. Even though the DPF is self-cleaning, it needs to be replaced after a certain number of miles to keep it functioning properly. For example, an OEM GM DPF fails after 70,000 miles.
