How often miners need to be cleaned depends on the environment that they are run in. In a dusty/dirty environment, they will need to be cleaned more often that is they are run in a clean computer center. In other words, it depends on your particular situation. I have air filters running in my environment and I do maintenance on mine about every 4 months.
