BREAS Z2 very noisy at mask
I normally use a Resmed Airsense 10 but I purchased a BREAS Z2 as a travel machine last year right before a vacation. It worked out terribly for me (too noisy) during that vacation and I put it aside when I returned and haven't used it until recently when my ResMed started acting up. Is there a reason that these BREAS Z2s are extremely windy and noisy at the mask? When I connect my hose and mask to the Resmed unit, it's so quiet that I sometimes have to pull the mask away from my face to confirm it's blowing. But when I conned the same hose and mask to the BREAS Z2, it is like a constant windstorm. The noise is emanating from the mask - not the Z2 itself. Also, I am using the inline muffler provided with the Z2. Does anyone know what the issue might be?
