@mb53 - Let me start by saying there is no such thing as a "self-cleaning" nebulizer when you are dealing with MAC & Bronchiectasis. Nebulizers, and all other devices like the Aerobika, need to be cleaned daily with soap and water, and disinfected weekly with boiling water, steam, or alcohol depending upon recommendations.

As for "travel nebulizer" there are two types
- compressor nebulizers (traditional type) which are more compact and lightweight than a tabletop model, and include a battery pack - usually rechargeable. These still include a neb cup and tubing, and may have the added advantage of being able to be run and/or charged in your auto.
- handheld nebulizers which use a mesh to break up the droplets and you breath directly through a mouthpiece.

Each has its own advantages, but the handheld ones you see on Amazon of $30 - 60 are NOT for daily use with meds plus saline solution - these are intended for occasional users of albuterol or an inhaled antibiotic during an brief illness or infection.

I will let others comment here, but my go-to for travel and everyday use is the DeVilbiss Traveler with battery pack, charger and 12v cord. I am on my third one, but only because my kids keep stealing them from me. It is quiet, reliable and long-lasting. It is a fast as the fastest tabletop nebulizer, and 7% saline doesn't cause it to clog. corrode or quit working. It runs 15-20 uses between charges, and costs a little over $100.

What kind of a nebulizer are you currently using?
