How to Clean a DPF Filter

Model: (Various brands) Various
Part: Cabin air filter

Video tutorial

In this video, see how professional cleaning of the diesel particulate filter is done, and how when water is sent under pressure into the component, it literally "erupts" like a volcano, expelling all the ash inside and cleaning itself, achieving 99% efficiency after a cycle lasting about three hours, returning to perfect condition, like new. The water used for washing is in a closed circuit: it is filtered and then reused for subsequent washes, meaning the same purified water is used each time.

The carbon residues are collected, compressed, and sent to specialised companies that recover them to make shoe soles and rubber coatings.
