Do you have unopened C-PAP head frames, face masks, nasal pillows, and headgear from trying them out but realizing they aren't a good fit for you and the provider won't take them back because it is too late?
I've been able to find some medical CPAP supplies for myself in the past at Bridge Ministries in Redmond and MSHH Donor Closet in Edmonds. Let me pick up your unneeded supplies taking up space and donate them so everyone wins.
And if you are looking, please reply back with the SKUs and/or close up pictures and I can pass on some opened but unused items that they can't accept.
