after waaaaaay too much time searching the FDA website (I'll never make my morning meeting now!!... EDIT: Thanks Goose )... I found the following info:
Class I medical devices do NOT require a prescription, but Class II devices do.
The P&B "NASAL CPAP CIRCUIT" is listed as an Anesthesiology mask and therefore classified as Class I (
http://www.accessdata.fda.gov/scripts/c ... m?&ID=1480 ) and regulation number 868.5580 (
http://www.accessdata.fda.gov/scripts/c ... R=868.5580)
Alternately their HH seems to be class II, but I couldn't determine whether it was a Class II Exempt device. (

Similar to the P&B mask, the Spectrum FFM from Respironics is listed as Class I:
http://www.accessdata.fda.gov/scripts/c ... ?&ID=21775
The Hans Rudolph is a Class I :

For Resmed, all I could find were "non-vented masks" so i guess that's not it:
http://www.accessdata.fda.gov/scripts/c ... m?ID=32832 ... maybe they are listed under another Manuf. name?
However Goose is right about the "Prescription use" box being checked on most of these if you look to the 501(K) Clearance report.... Also I noticed somewhere else on the FDA site (can't find the link back though) that if you go to another link about the CPAP mask, it goes the device classification description of the CPAP itself (which *is* a Class II regulated device).
So I dunno!!! I'm confused, tired, and don't care anymore, as long as the government leaves us alone! (which isn't likely to happen... I mean look at their control of even herbal and vitamin supplements!!! It's getting worse every year....)
