Philips CPAP & BiPAP Machine Lawsuits
Millions of Philips Respironics CPAP, BiPAP, and ventilator machines were recalled after the foam used to reduce sound was found to degrade and release toxic, potentially cancer-causing particles directly into users' airways.
The Philips Respironics Recall
In June 2021, Philips Respironics issued a massive recall covering approximately 5.5 million CPAP, BiPAP, and mechanical ventilator devices in the United States — and an estimated 10 to 15 million devices worldwide. The recall was triggered by the discovery that the polyester-based polyurethane (PE-PUR) foam used inside the devices to dampen sound and vibration can break down over time, releasing black particles and chemical off-gases directly into the air pathway that users breathe through every night.
Testing confirmed that the degraded foam releases volatile organic compounds (VOCs) including known and suspected carcinogens. The FDA classified the recall as Class I — its most serious category — indicating that use of the affected devices may cause serious injury or death. Lawsuits allege that Philips knew about the foam degradation problem for years before issuing the recall and deliberately delayed warning the public.
"The polyester-based polyurethane (PE-PUR) sound abatement foam, which is used to reduce sound and vibration in these affected devices, may break down and potentially enter the device's air pathway. If this occurs, black debris from the foam or certain chemicals released into the device's air pathway may be inhaled or swallowed by the person using the device."
How the Defective Foam Causes Harm
The PE-PUR foam inside affected Philips devices is designed to absorb sound and reduce vibration. Over time — and especially when exposed to heat, humidity, and ozone-based cleaning devices — the foam breaks down into small black particles that enter the air pathway. Users inhale these particles and the associated chemical off-gases with every breath they take during sleep therapy.
The chemicals released by degrading foam include diethylene glycol, diisocyanate compounds, and other VOCs that are toxic to the respiratory system and have been classified as potential or probable human carcinogens. Because CPAP and BiPAP users typically run their devices for six to eight hours every night, cumulative exposure over months and years can be substantial.
Health Conditions Linked to Philips CPAP Exposure
Lung Cancer
Inhalation of carcinogenic VOCs and foam particles over extended periods has been associated with elevated lung cancer risk in CPAP users who relied on affected Philips devices.
Throat & Tracheal Cancer
Toxic particles and chemical off-gases pass directly through the throat and trachea during use, and cancers of these structures have been reported among affected device users.
Kidney Cancer
Certain VOCs released by degrading PE-PUR foam are nephrotoxic and have been associated with kidney damage and elevated renal cancer risk with prolonged exposure.
Respiratory Irritation & Damage
Many users have reported headaches, upper airway irritation, coughing, chest pressure, and difficulty breathing — symptoms consistent with repeated inhalation of toxic particles and gases.
Liver Damage
Some VOCs released by the degraded foam are hepatotoxic. Liver enzyme abnormalities and liver damage have been reported in users of recalled devices.
Neurological Effects
Certain chemical compounds released by the foam have neurotoxic properties. Users have reported cognitive changes, dizziness, and other neurological symptoms associated with prolonged exposure.
Affected Philips Devices
The recall covers a wide range of Philips Respironics devices used for sleep apnea therapy and respiratory support, including:
CPAP Devices
DreamStation, DreamStation Go, DreamStation 2 (certain models), System One (50 Series), REMstar SE Auto, REMstar Plus, REMstar Auto, REMstar Pro, and others.
BiPAP / BiLevel Devices
DreamStation BiPAP Auto, DreamStation BiPAP Pro, DreamStation BiPAP AVAPS, System One BiPAP, and related BiLevel therapy devices.
Mechanical Ventilators
Trilogy 100, Trilogy 200, Garbin Plus, Aeris, LifeVent, and other ventilator models used for life-sustaining respiratory support.
Who May Have a Claim?
You may qualify for a claim if you used a recalled Philips Respironics CPAP, BiPAP, or ventilator device and have been diagnosed with cancer, experienced significant respiratory illness, or suffered other serious health conditions linked to foam particle or VOC exposure. Claims may also be available to users who have not yet been diagnosed but have experienced symptoms consistent with toxic inhalation.
Philips has faced thousands of lawsuits and a major multidistrict litigation (MDL) has been established in the Western District of Pennsylvania. Philips has reached settlements in some cases, but litigation continues for many claimants. Our attorneys are actively investigating claims and can advise you on your eligibility and the deadlines that apply in your state.
