Philips DreamStation recall (June 2021): polyester-based polyurethane (PE-PUR) sound abatement foam degraded into particles and off-gassed VOCs (toluene diisocyanate, formaldehyde) — inhaled directly by 3-4 million users. FDA Class I recall (most serious). Ozone-based CPAP cleaners (SoClean, Lumin): produce ozone (0.05-0.5 ppm) that degrades rubber and silicone components, accelerates foam breakdown, and is itself a respiratory irritant — FDA issued safety communication warning against ozone CPAP cleaners (2020).
