The Best DPF Cleaners 2020

Diesel particulate filters capture and store exhaust soot for improved emissions but when they go wrong, they can cost thousands to fix. However, with the use of a DPF cleaner, you are able to improve the stability of the system and restore performance.

Best DPF Cleaner

Diesel particulate filter systems trap and hold any harmful emissions from your car. The stored deposits are then burnt off at extremely high temperatures into harmful ash, which is a process called DPF regeneration and it usually happens at speeds over 50 MPH. However, if you don’t achieve these speeds on a regular basis, it can lead to the DPF becoming blocked. This is where a DPF cleaner becomes very useful at it’s designed to clear the deposits blocking the filter.

The best DPF cleaner is the Forte DPF Cleaner and Regenerator, which is suitable for all diesel engines and aids passive regeneration of the diesel particulate filter.
