I change the filters on mine about one a year.
Also seal it in a large plastic bag when not in use to help keep the crude out of the facemask area.
Filters are cheap and replacable. Your lungs are a different story.

I use a North 7700. Clean it monthly. Change filters about every 6 months. These cost a bit more than the 3M ones. They are both 0100 & gas vapor filtering.
