Hi @jeanarizona - perhaps you have disposable nebulizer cups instead of reusable nebulizer cups? There are 2 types that I alternate that can be boiled (linking to a site but there are many places that offer them online without a prescription.) Save your disposable nebulizers for travel.

I use these nebulizers with the Ombra compressor. This setup allows me to use the aerobika inline (at the same time) with the nebulizer. Saves some time. This setup is recommended by National Jewish Hospital, a leading respiratory hospital that takes care of bronchiectasis/MAC patients. I'm sure others will weigh in with their preferred equipment.
