This was purchased for a friend I currently take care of. His previous assembly was too plugged to be used, even though we could not find any visual blockage. So I purchased a replacement and it works flawlessly for him.
This is just what I was looking for. Received very quickly. Would recommend and I will use them again.
Very quiet!! And fast , has cut the treatment time down considerably.
The Pari ProNeb Max works very well when one does a lung treatment.
That is the only kind I ever purchase.
