Your DME should set you up with what they feel is best for you. I didn't have any say in my original machine and mask. I have since tried several different masks (settled on nasal pillows and nasal mask backup) but my machine is the original. From what I understand, you should be on a trial period with your DME and if anything isn't working for you, they should change it out.
Good Luck!
