I really don't know. There may even be a particulate sensor in there that triggers at a certain level.
Or, it could be like the filter change light in my fridge. It alarms regularly(every few months). Of course, it isn't hooked up to anything, so it's only telling me that a certain amount of time has passed since I last reset it
