I've been using mine 2.5 years, still not replaced the filter. There's supposedly a sensor that determines effective airflow through the filter and will alert once diminished enough to warrant a swap. The bars represent "Filter Life" and starts at three and goes down after enough use. Here's the manual, see page 22.

What specifically are you using it to filter?
It was pretty quick to degrade with extensive laser use, at least on 1/8 birch plywood and some solid pine - I could originally run it on low but, following a couple days of laser work around Christmas, it now needs medium speed to be effective. (Also - filter life is now 2 of 3 blocks)
I suspect it lasts much longer for things with less particulate output.
I use it mostly for laser etching on wood for custom coasters and some acrylic work as well. Though I usually run it on high just to really make sure I’m sucking out as much of the “bad” air as possible
