I have the same problem. I don't filter though. I have so many E-mails in my inbox that are completely and utterly pointless, that I just haven't taken the time to delete. Literally, 122 pages of E-mails that I have to cut down eventually.
I've got thousands of unreads in my actual Gmail inbox. They're all forwarded to Yahoo (which I can access from work) and I've been ignoring Gmail since about January. >.>
