This system is also maintenance free. A much better system than DPF/diesel particulate filter which has to be serviced regularly or replaced which is expensive or a DEF/diesel exhaust fluid which you continually have to purchase.

Hi, How do I get one of these for my stinky 5kW diesel generator? Do they cost more than the generator itself? Thanks

The announcer made a mistake.
He said the scent of burnt diesel was obnoxious.
I am sure he meant awesome.

Awesome yet carcinogenic.
