I apologize, I did not see it on Amazon even though it pulls up the category for it.
Google it as Monaghan Z STAT . It is an aero chamber that allows the medication to be delivered more efficiently. I personally prefer not to order non-medical "stuff." Monaghan is a medical company out of Pittsburgh. They are no very expensive ($9-$12) and provide explicit direction on how to use, clean etc. In fact your physician should probably have some samples left by the company's Representatives that visit them. It greatly enhanced my inhalations with a noticeable difference! I will try to figure out how to take a picture of one and attach it in my next message.
