Definitely keep it running for as long as you can. Personally, I like to keep two filters running all the time. If one craps out, and it has happened, I still have one running, and my tanks are sparkling all the time. I also have an "extra" filter any time I want to use one to seed a new tank, and I use this method to rapid cycle new tanks frequently. I just cycled a tank in 5 days borrowing an existing filter and a few handfuls of substrate from a long-running tank along with the product "Cycle".
