[CPAP] Is my new A10 defected or is the noise normal?

I'm using an A10 Autoset, with EPR set at 3. I can hear air whooshing on inhale, and nothing on exhale. Lately, with my Wisp mask, I can hear some mask noise on inhaling also, but it gets less noticeable by the time I wake up.

I may try recording it some night, to see if it picks up mouth breathing as well.

Precisely, Phil. A loud noise from the back of the machine on inspiration, but a low level on expiration. The noise is not from the hose nor the mask.
