Newbie Filtration Question

How often do you change your filtration? I’m running with Filter Floss (blue & white pad), purigen & chemi-pure blue in a 20g nano.
I don't run mechanical filtration all the time. Just when I want to clear the water column. May do this a few times a month and/or if the sand bed gets churned.
