Chiming in: I find the best way to figure out how to clean/sterilize nebulizers etc is to follow manufacturer's instructions. There's great info here on how/when to clean/sterilize but I find everyone manages differently. How rigorous you clean/sterilize all those plastic parts is dependent on disease state/status. For example, if you're fighting pseudomonas/MAC perhaps cleaning/sterilizing daily would provide peace of mind. If you're stable, then maybe once a week is ok. Those who are risk averse will sterilize everyday. Asking your doctor or RT is a good place to start.
