Travel saline/nebs

I was considering options for travel and know that the Pari trek comes highly recommended, of course sterilizing equipment comes into play (I think there might be disposable cups which might be useful to use?). I also recall reading someone said their Dr approved just using their albuterol inhaler instead for travel. It got me wondering if there was an inhaler for hypertonic saline as it seems like this could be a good short term delivery method. Google brought me to this: Boogie Micro-Mist Saline Inhaler, Baby Nose Congestion Relief, Nasal Spray for Kids. Does anyone have any experience with this? It’s isotonic 9% saline. While it has up to an hour of treatment it seems like it would be hard to measure how much you are getting per session. Not cost effective for daily use but certainly less bulky than packing up all the daily supplies.
