It uses fuel to burn the captured diesel soot, then it does produce soot that is 1 to 2 micron which is most hazardous.
My old diesel, what soot it makes is big 100 to 150 micro. You can see it and smell it and that's a good thing, our bodies can stop almost all of that before it gets into our lungs.
The problem with the 1 to 2 micron size, that's the size chemical weapons manufacturers are going for, so it gets inhaled deeply into the target's lungs.
