# purchase an in-line antibacterial filter ''(search for "antibacterial filter for cpap" on Amazon or another site)'' to catch any and all foam particles. Note that this will do nothing for the off-gassing.

# purchase a new non-affected CPAP that is the equivalent or upgrade of your current machine. Word is trickling out that at least some insurance companies are allowing replacement prior to the 5-year lifetime. Call and ask, you likely will need a prescription and possibly a justification (the Do NOT use Recall) note from your doctor, again ask.

# For questions please as on your favorite Apneaboard forum.
