A filter is just that; it filters debri and impurities in order to keep the oil clean to a certain degree for as long as possible. The condition of your filter is directly proportional to the condition of your oil because your oil is continously being run through the filter (and impurities). If the oil is dirtier or equal to the amount of impurities on the filter, it will either shed it's impurities or pass through untouched.
Putting new oil into a car and not changing the filter will result in the filter giving it's impurities to the new oil; making it just as dirty as the oil that was in it before it; therefore making the oil change useless.
If you have a fish tank, imagine it like that. Changing out the water to control impurities and waste is great and all, but no matter how pure the water is, the second it passes through a dirty filter, it will pick up all the dirt the filter has.
Your oil is only as clean as your filter is basically.

Thanks for the clarification... Didn't know that... Over here ppl only change the filters every other oil change... :P
Right now, I'm guessing that's bad practice....
