i use provent nasal for EPAP for OSA last night
No need to worry about this.
Thanks for your question on 'Ask A Doctor' forum.
I can understand your concern.
As such, no need to worry about this. You have not caused any pathology or damage to those filters with the sneeze.
Actually, these mask and filters are protected against these kinds of wear and tear.
So, they can certainly sustain them...No need to worry, no damage likely to these structures due to any form of sneezing.
Hope I have answered your query.
I will be happy to assist you further.
Wish you good health.
