Manufacturer Reason
for Recall
Philips has identified a specific lot of non-conforming material manufactured by one of its suppliers. A Philips supplier incorrectly used polyester-based polyurethane (PE-PUR) sound abatement foam, a non-conforming material in the devices and repair kits. PE-PUR foam may degrade into particles which may enter the device s air pathway and be ingested or inhaled by the user. The foam degradation may be exacerbated by use of unapproved cleaning methods such as unapproved ozone cleaners, and the PE-PUR foam may off-gas certain chemicals during initial use of the device.
