When I get a new device, I'm going to kind of do the same thing. I'll keep my old one in the living room so I can use it during the day, but a new one I'll use in the bedroom when I hit the sack for the day. Hopefully I can get another RedMed so I can use the same mask type in both locations.

Thanks for your comments.

I think you should be able to use about any brand of mask with any brand of machine.
