nearly six month after the recall was announced, it turns out there’s a safety concern with the foam being used in the proposed replacement devices:
So now it’s anyone’s guess as to when acceptably safe devices will be available to replace the recalled devices currently being used by patients.
I was originally planning to just wait for a replacement, but now that the timing is up in the air, I’ve decided to pull the foam from my CPAP’s plastic intake manifold. There are plenty of YouTube videos out there that show how to do this (including how to take the CPAP machine apart so you can get the manifold out to work on it), but they all involve cutting or grinding a portal in the side of the manifold through which to remove the foam, followed by a messy patch involving epoxy or hot glue. OTOH, this guy used a tool for pulling hair clogs from drains, and and was able to get his foam out without any cutting whatsoever.
Philips included the foam for noise control, but the increase in sound level from users who have removed the foam is reportedly negligible. So now I’ve bought a drain weasel and will be doing the same thing to my CPAP.
