Just have a look at it, and when it's dirty, change it. The time factor is really just in conjunction with the mileage, and how dirty the air has been around you while driving. If you don't drive much, and you're in a clean air area, it'll last longer than if you live on a dirt road or there have been wild fires around you, etc. Thanks for the comment.
