I am still in the testing phase. I spent about 2 weeks with a Philips Respironics 60 Series Pro CPAP. I have spent another week with a Resmed A10 Elite. At first I thought the A10 was very quiet but it seems to make very audible "breathing" or "air movement" sounds as I breath. There is also a slight, faint whirring sound. I don't remember the Philips being as loud... Is it just me?
As far as everything else goes, the Resmed is pretty good. The smaller footprint, the bright coloured screen that gives me feedback when i wake up, the much easier to access, fill and clean moisturizer, the better functioning moisturizer, are some of the things I find better than the Respironics.
Ford / Chevy. I mean what oil do you put in your car?
The machines are different but the number of people that actually have a choice, let alone a basis of comparison is very small.
My question is only about the noise they make.
