AirSense 11 makes "puffing" sounds after power off
AirSense 11 makes "puffing" sounds after power off
I have a new AirSense 11 machine with humidifier and heated tube. When I turn it off in the morning it makes 3-4 "puffing" sounds about 30 minutes after being turned off. I know that it needs to "cool down" and it quietly blows air after it turned off (same as AirSsense 10 did). However, AirSense 10 just stops blowing when it is done where as AirSense 11 makes these 3-4 loud "puffing" sounds at the end of cooling cycle. Is this normal? Any way to stop these noises? Thanks.
