Trio verses erapid are they interchangeable


New member
I have a trio for Tobi but I am told it is rented and can only be used for Tobi. Anyone have a Trio and Erapid know if the medication cups can both be used with the Trio base and Trio connector chord. I would like to buy a couple erapid medication cups and not buy the ebase if they are the same.

Also anyone with an Erapid how often are you replacing neb cups? How often are you replacing the metal head? How much do these cost?
