I was looking through the wiki and came across this paragraph:
However, the papillow.com website redirects to some gaming site. With search being full of AI crrrap, I'm not seeing any search results for CPAP pillows that look trustworthy.To make a mask more comfortable, consider Pad-A-Cheek strap covers http://www.padacheek.com/ , a mask-compatible pillow such as PAPillow http://www.papillow.com/ to reduce leaks, proper hose management so there is no drag on the mask causing leaks; a PAP heated humidifier, fleece hose cover, Australian SleepZone heated hose http://www.sleepzone.com.au/index.html, and hose connectors. See the articles on Solving CPAP Mask Problems and Solving Common Equipment Problems.
I didn't join to find out about pillows, but now I wanna know.
