The Department of Health received a notice today (16th) from the manufacturer Philips Respironics that the soundproof foam of its respirators is prone to degradation and release of chemical gases, and it is voluntarily recalling certain types of respirators.
The ventilators are used to treat respiratory conditions, including obstructive sleep apnea. About 20,000 units of the affected devices have been sold in Hong Kong.
Sound insulation foam can be degraded into particles for users to ingest
