The PE-PUR foam in recalled Philips devices releases chemicals that affect the body in two ways: immediate local irritation of the respiratory mucosa and delayed systemic carcinogenic effects following absorption into the bloodstream. Symptoms can vary significantly based on how long you used the device, whether you used ozone cleaning, and your individual health status.

Non-cancer symptoms reported by CPAP recall plaintiffs include chronic headaches and migraines, eye and throat irritation, chronic sinusitis, nausea and dizziness, worsening of COPD or asthma, and chemical sensitivity. Cancer warning signs to watch for include: unexplained nasal congestion or nosebleeds (nasopharyngeal), persistent cough or hemoptysis (lung), blood in urine (kidney/bladder), right upper quadrant pain or jaundice (liver), and enlarged neck lymph nodes. Any new or persistent health symptom in a recalled device user warrants immediate medical evaluation and legal consultation.
