From a quick search of the FDA's adverse event database I only found five reports of events relating to the Philips Dreamstation from before 2020; only the fourth could related to the foam-dust: One relating to filter problems: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/detail.cfm?mdrfoi__id=6442292&pc=BZD&device_sequence_no=1 https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d... One relating to skin irritation: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/detail.cfm?mdrfoi__id=6820488&pc=BZD&device_sequence_no=1 https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d... One with WiFi connectivity issues preventing configuration(!): https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/detail.cfm?mdrfoi__id=7179053&pc=BZD&device_sequence_no=1 https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d... One waking up with a burning sensation in their nose and throat: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/detail.cfm?mdrfoi__id=8069558&pc=BZD&device_sequence_no=1 https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d... One shut down during the night leading to too-low oxygen levels leading to hospitalization and death: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/detail.cfm?mdrfoi__id=8475436&pc=MNS&device_sequence_no=1 https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d... It boggles the mind that Philips would chose to report the WiFi complaint, but not the foam-dust complaints. To me it makes it seem even more likely that this issue was deliberately suppressed by management.
