@sueinmn, I received the pari E flow when I was approved for Arikayce . I wonder if when i am done with Arikayce if I can use it for my hypertonic saline. But how long can you use the golden colored mesh part that goes in the hand- held part? While doing Arikayce, they have me change it weekly & I get enough (4 in box) for a month, & also a new handset every month with each Arikayce monthly med box...
