I realize this is where the airway is opened so we can breath normally, but where do these airborne items end up? Where else could they go? Now consider my situation. I used the grey coarse filter for several months, the combined accumulation of what passed through is concerning to me as a possible contributor to my current situation.
Let me address this separately. Some of the dust in the filter would have ended up in your lungs. Most of it would have gone out the exhale vent without ever touching your lungs.
Without CPAP or apnea, you would have inhaled at least the same amount of dust as you did with CPAP without filters.
However much dust you're breathing through CPAP while asleep, you're breathing more dust while awake than while asleep, because you're awake for more of the day, breathing deeper, and probably doing more things to stir up dust.
