Filter change on Bipap machine

[kfujioka]

I have a System One (Respironics) Bipap Auto Biflex machine; and I just noticed the filters have fallen out. One is a rectangle sized black foam and one is a thin white one with words on one side. I can't figure out how to put it in. I assume the thin white one goes in first and the black foam one on the outer side. But I wonder: does it matter what side the thin white filter faces ? Should the side with words on it be facing the foam filter or facing the machine?

I read the machine booklet several times and it doesn't say.
Would anyone on here know?
Thanks

From Supplier #1 ... Tips for inserting filters:

1. If you are using the disposable white filters, insert it into the filter area first, mesh-side facing in, towards the device.

2. Insert the gray foam filter into the filter area, on top of the fine filter.
