Devilbiss 9200DI-H Heated Humidifier with Hose

Has anyone used the Devilbiss 9200DI-H Heated Humidifier?

I was wondering about the water chamber. Does it come apart like the Respironics humidifiers?

How well does it work? Any problems?

I was wondering if you have tried this humidifier and how did it worked for you?

Take care, Willie. According to cpap.com, It's the 9100 with a 9200 heater, and the following appears in Devilbiss's submission to the FDA about the 9100:

http://www.fda.gov/cdrh/pdf/K003626.pdf

The DeVilbiss Humidifier is not intended for use with autoadjusting CPAP devices that use snoring, as detected through the patient air circuitry, for the adjustment of the therapy pressure. The humidifier is know to attenuate the snoring frequency signal as it passes through the humidifier and the patient circuitry, which prevents the autoadjusting CPAP device from detecting most snoring.

Note, this is on a formal DeVilbiss document submitted to the FDA.

That's interesting, ozij. Am glad you found and posted that. Caused me to add to a reply I had made in another thread just before reading what you found.

I'll say the same thing here that I added there... lol.

"There" being an old topic that resurfaced when Krunal asked about the separate DeVilbiss heated humidifier:
viewtopic.php?p=367679#p367679

In my reply there, I added this:
I don't know if the same kind of caution against using that stand-alone humidifier with an AUTOpap applies also to any stand-alone humidifier (like the F&P humidifier.)

Personally, I wouldn't hesitate to use either one (the F&P humidifier or the DeVilbiss) with any autopap myself -- regardless of the caution in the DeVilbiss FDA application. But, that's just me. And, as I said, I haven't actually tried the DeVilbiss humidifier, so I don't know if I'd get different results from what I get using the F&P with my autopap.

The DeVilbiss has a much larger surface area for the air to go over, so that might make a difference in how the snore signal was affected, compared to the smaller surface area of the F&P humidifier.

My results have been essentially the same using either the F&P humidifier or the integrated humidifiers for both the older REMstar Auto and the M series Auto, and with a ResMed S7 Vantage autopap. I guess "mileage would vary" for some people.

When the Puritan Bennett 420E autopap first came out (and for several years thereafter) they did not even make an integrated humidifier for that machine. They recommended using the separate F&P humidifier with it. That autopap also processes "snore" signal. Maybe they worked their algorithm to account for use of a separate humidifier, and had the F&P in mind, though. So... your guess is as good as mine.

I would expect the humidifier's shape to have a clear impact on the sound that travels in it. So the DeVilbiss "no" seems reasonable to me, even if the F&P is "yes".
