Hey Jim, if you're able to pay for it yourself, I would do it. But, at minimum and before that, if your pulmonologist refers you to the pap and accessories company your insurance covers, (ours is APRIA Healthcare), he/she can order a fitting (by appointment) of the Dreamwear mask which you need anyway. The fitting is done by a respiratory therapist or resp tech. Then you can get to know the product and which size is best. Both the soft area (cushion) that sits up against your nostrils (one hole for both nostrils, so soft and pliable you won't believe it!) , and the frame the cushion is attached to, have sizes. So you need to know your size for both pieces which you will learn at your appointment. I think you can get them on Amazon but need to really know what you want and need. You can get the referral and the fitting should be covered if you tell your doc that what you're using is problematic.

I really hope that at minimum, you get the fitting and can experience the product.

Let me know! All the best, Sunny. 😊
