Many people use the Ombra or Pari Pro Neb Max which are the compressors that nebulize (create the aerosol or mist) by pumping air through the liquid placed in the "cups" which are called nebulizers. There are several different types of nebulizers (cups). Sometimes we have to try a few different types of brands to find one that we like. Many people use the Aeroclipse XL BAN, some like the Pari Sprint or others. Make sure to read the info before purchasing to see that the cups (nebulizers) state that they are reusable after cleaning. I listed a couple of websites to get started with. There are several other medical companies online that carry these products.
