Thank you. I will try to boil my Swift FX Nasal pillow.
I have taken a large pot of water, brought it to a boil, turned off the heat, and dropped all the disassembled Swift FX parts into it and left it to cool. I haven't boiled the foam/fabric headgear.
Also, ComfortGel, ComfortGel Blue, Oracle Oral mask, ResMed legacy, M series, and PRS1 tanks.
The S9 CLEANABLE tanks survived OK. The newer S9 standard tanks were ruined. The older style S9 standard tanks that didn't open easily were OK.
Someone posted that P10 cushions melt if boiled.
Some hoses, especially clear plastic "short" hose as part of masks may be damaged. Normal hoses seem to get "crinkly," but don't completely melt.
Of course, don't do the boiling step on anything you can't stand to lose. Even if one person got away with "boiling" a particular CPAP part doesn't mean they haven't changed the design and your part may melt. Or that your part may crack or something.
There are some ResMed and Respironics sanitation guides in the Useful Links in my signature line at the bottom of this post.
