Furnace filters for 2017 Winnebago Tour

2017 Winnebago Tour
Do I have furnace filters if so where? I’ve been cleaning the over head ones, but thought they are just for the ac. Speaking of that, when I was cleaning the round vent filters one was black,. I have no idea which spot it is supposed to go back to???

No, the propane furnace does not include any filter.

As to one black round A/C filter? That sounds like something a previous owner added or created or sourced on their own in a pinch as a replacement from the usual gray filters.

I replaced my OEM filters with aftermarket filters that are white with a green layer. That should really confuse some future owner.

I don’t have propane. I have heat pump and diesel heat.

My sister-ship Ellipse has the return air filters in the cabin ceiling for the roof-top heat pumps that we clean about 3 times a year traveling FT. There are no known filters for the diesel heat (AH). The AH heat exchangers do need cleaning by removing the grill and using a soft brush vacuum cleaner. On our coach with no pets / kids we do them once a year along with the RR grill at the bottom. On a friend's coach with dogs they do it about three times a year.
