The volara gets in pretty deeply to the lungs. It’s also a quick therapy. Cons are that it’s more stuff to clean and the hose can’t be boiled or steam sterilized.

I haven’t been using it lately because I suspect it aggravates my hemoptysis. Next week i follow up with my pulmonologist so will ask him about it.

Since I have learned more about airway clearance techniques from videos on this site I don’t feel as much need for it. Postural drainage, exercise (walking, resistance bands, and things like qi gong) and breath holds work especially well for me and are gentler.

I hope you find what helps you!
