To be clear, the message definitely says DEF filter. My truck just hit 250,000 miles. Doesn't look like I need any other maintenance until Sept. Luckily I'll be near a terminal for this one. I know some drivers like to avoid terminals but, I think I'd rather wait at the terminal than at the nearby International place (Five Star in Allentown, PA)... I've spent a day there and the lounge wasn't great. The Peterbilt places I've been to had really nice waiting areas. International might have some nice places and Peterbilt might have some ratty ones. I haven't been to all of them.
A DEF Filter is a pretty simple fix. It's just an inline filter for the DEF Fluid system. It's neither very costly nor time consuming. If it's coming up as a SCHEDULED MAINTENANCE, rather than a CHECK ENGINE CODE - then you can do it at your leisure.
They're a common enough item, that you might even find truck stops that you have contracts with, able to swap it out for you.

A facility where trucking companies operate out of, or their "home base" if you will. A lot of major companies have multiple terminals around the country which usually consist of the main office building, a drop lot for trailers, and sometimes a repair shop and wash facilities.
