Insmed Incorporated manufactures the Arikayce and Pari provides the delivery device, aka eFlow, they call it "Lamira". I do not use Arikayce so I do not know how the eFlow and Lamira compare. I do know that the Pari eFlow can be used for saline (I have one and I use it everyday, purchased it outright). It might be that the handset delivered with Arikayce has a different handset than the standalone eFlow.

I also thought it was just for Arikayce and would love to find out if I can use it for levalbuterol and 7% saline as it seems it's faster and quieter. Did you get any info on this?
