Does the E450 Super Duty have a pollen filter?
While it does not have one or a location for it, just for reference, some vehicles that don't come with one in the US still have a spot for them.
We had a 2003 Ford Focus that didn't come with one but it was standard in Europe. Easy to install.
We have a 2003 Chevy tracker that didn't come with them but same thing - other countries had them standard. A few dollars later from Amazon and I had them installed.
It indeed makes a difference in less dust through the vents and the dash stays cleaner. Family members with pollen allergies appreciate the bonus.
