Remstar Pro M Series question

[newname]

I just took my machine out of storage after 3 years becasue I've been using a Legacy.
I just noticed that the Remstar Pro m series doesn't have a plastic cover over the foam filter. Is it supposed to be this way or did the cover get lost?
Maybe I'm getting confused because the LEGACY has a plastic cover over the foam filter.
If anyone has the Remstar Pro m series could you let me know if it should have a cover. I put in the white disposable filter then the gray foam filter and it seems like there should be a plastic cover to go over this. Thanks

It was ok but no data, when I got my first one 2 months after hers it was a PR System 1 Pro. I shamed the DME to upgrade hers to a PR System1 Auto.....
