The Devillbiss Pulmoaid I believe is approved for both of those meds. We have both nebs and primarily use the proneb II for travelling 'cuz it's so compact. After hearing comments on this site about it, I've been waiting to see if similar things happen to it. We bought the Devilbiss after continued issues with his orginal proneb ultra I, treatment times -- tobi took forever 45-50 minutes from day one and being new parents, we never knew that wasn't supposed be.
