Reports of off gassing from AirSense 11
I had to return my AirSense 11 last week. The machine worked well but the smell of the air output is not just unpleasant, it is a chemical smell reminiscent of overheated circuitry in amplifiers I deal with, like a transformer going bad. The smell also is a bit like a very cheap multimeter I bought that had a horrible smelling plastic cover. A mix of cheap plastic and overheated electronic circuitry is what I smell and I lost much of my ability to smell anything so it must be pretty strong.
The smell is most noticeable, and quite disturbing, taking the mask off after waking. I've heard of one other CPAP user having getting the same smell from the outflow of air from the machine, not the machine itself.
Out of five CPAP machines. This AirSense 11 is the only one to ever produce any odor at all. Even my recalled System One did not have a smell to the air output.
I can only guess that the new plastic of its structure is off gassing or gas from the air pump and its circuitry is getting in the output. I don't think the silicone seals would do it. I do not know if it is toxic, but I can not handle it so back to a new AirSense 10 I have gone.
I told my local DME about it. DME said there are several customers who are happy with their AirSense 11s with no complaint of a chemical like smell from them.
I am disappointed about one thing with this new AirSense 10. It does not have the same tube connection as my old AirSense 10. The old one accepted a tube that did a 90 degree turn that was good thing for my set up. Also, the non heated tube I got with the unit is very stiff which is very disappointing. I hope the maker gets on the ball and provides better tubing. The tube could be a DME thing though. My DME may have another source for non heated tubes and use cheap stiff ones. I've had cheap garden hoses that are more supple than the one I got.
Please let me know here if any one else is experiencing an acrid, chemical like smell in their therapy air from a machine. Maybe I got a defective unit as maybe did another CPAP user who gets the similar chemical smell.

I only give suggestions from experience as a fellow CPAP user, not professional advice.
