I have been really frustrated dealing with DME providers and insurance for my CPAP supplies. I was long overdue for some filters and a new nose pillow for my Dreamstation 2. I did not know I could order those things directly until I found 1 800 CPAP. I ordered what I needed and had it in hand within 3-4 days as described and in OEM packaging. I will be using them for all of my CPAP needs in the future. Happy customer!
