I heard there are 2 different part numbers from this thread,
the difference being the length to accommodate the extra length created by the
m diffuser.

And I found 3 different part numbers online and I'm not sure which is which.

What I have right now, part number 7 602 290.
Which is the right one? I have the standard diffuser.

And all of them are valved, right? How loud are they in comfort mode? Don't want to wake anyone up in the morning.
