@margiebanks Margie....I have been just tossing my nebulizer into a pot of boiling water after each use. It's the acapella cleaning that is a little much. I had seen the suggestion for baby bottle sterilizer before. Certainly more of a draw now with the acapella. I will be curious to see your response to the acapella. It does a great job in removing phlegm that I am dead sure I would not be able to do on my own.
