@johnwpatrick To further clarify: the nebulized version of the "puffer" albuterol is called levalbuterol (link below). To get started with nebulizing you'll need:

1. compressor: tried and true is the Ombra compressor, which is a jet compressor. This plugs into the wall. There are other options but this one is the most popular. Does not require a prescription.
2. nebulizer handset, which "plugs and plays" with the Ombra, called Aeroeclipse breath activated. Does not require a prescription.
3. aerobika - oscillatory PEP (Positive Expiratory Pressure). Does not require a prescription.

The aerobika slides onto the end of the nebulizer handset, so that you can nebulize saline and use the aerobika PEP device at the same time.

Many people use hypertonic saline, either 3% or 7%, which requires a prescription, but is not covered by insurance.

Here's a video by one of our members showing how it all works together:

Here are a few links to one vendor who I have purchased from before but there are others. Let us know if you have follow-up questions.
