sorry to ask silly things...
when you say the "star", is this some sort of online facility offered by MB? How do you access it? Is it via a web site? If so, can you give the address?
Thanks in advance.
Also when u said "vacum source to collapse the seal", I believe you are refering to changing the charcoal filter and not the pre-filter. Correct? As far as I know, you can just change the pre-filter without using any vacum tools.
