When a pet store tells you to do that then it is safe to throw out any info they have ever given you or will ever give you. The filter companies tell you to change out the filters often in order to increase sales and get more profit. The only time you need to change out the filter cartridge is when it is literally decaying and falling apart.
So to keep a tank a weekly water change is an important part of keeping a tank healthy. Weekly 50% water changes are the best way to go. As for the filter clogging up, like I said before just swirl it around in the water from a water change.
What fish do you have in your tank?
Also, what plants do you have?
