I have a philips dreamstation cpap machine serial #: (b)(4).On a couple of occasions over the past couple of months, i have found a black graphite-like substance clogging the temporary and permanent air filters.The substance permanently stains the filters and cannot be washed out.The filters must be destroyed.Disturbed about the substance, i notified (b)(6) who told me not to worry about it.Last week i received a letter from philips stating that the sound abatement foam they used was degrading and could be inhaled.They instructed me to complete a form and noted the company was "deploying a permanent corrective action." phillips did not state what the corrective action would be nor did they provide a time-frame for this corrective action.How do i know if i inhaled any of the chemicals? i am appraising the fda of this situation.I know nothing about the remaining test questions on the form.Fda safety report id # (b)(4).
