I wonder if "cleaning materials" means a chemical, like a spray, or something different.
- petejansson 3y agoA few years ago, there were a number of devices that came on the market that essentially blew ozone through the airflow pathways in PAP devices, and this was supposed to be a substitute for disassembly and scrubbing (which is a lot less convenient). While nobody has said these devices and the ozone methods actually damaged the foam, replacement PAP units all are not warranted if ozone cleaning devices are used. I don't know if this is the only "cleaning material" to which the article refers.

- jaclaz 3y agoVery likely some cleaners also have some solvent, though there is an explicit warning about UV and ozone[1] sanitizing: https://www.fda.gov/medical-devices/safety-communications/certain-philips-respironics-ventilators-bipap-and-cpap-machines-recalled-due-potential-health-risks https://www.fda.gov/medical-devices/safety-communications/ce... https://www.fda.gov/medical-devices/safety-communications/update-certain-philips-respironics-ventilators-bipap-machines-and-cpap-machines-recalled-due https://www.fda.gov/medical-devices/safety-communications/up... but I believe that more than anything else is the quality of this PE-PUR foam that is lacking. [1] ozone sanitizing treatments have been found to damage a lot of materials (besides metal which oxidizes very quickly also rubbers) and actually ozone chambers are used to test rubber materials durability
