@heffers Welcome to Mayo Connect - there are a number of nebulizer discussions in this support group, and the consensus seems to be that the highly portable mesh nebulizers (like the no longer made Innospire Go) that are on the market have one of two flaws - either they don't last, or there is no way to sterilize them. I would also suggest that a solution which you mix yourself would be likely to clog the mesh screen quickly.

Many of us have found small portable battery operated compressor style nebulizers are a good alternative. I favor the DeVilbiss Traveler, which can be charged up and used for a week or more. Others have good results with the Pari Trek S, but say the battery may not last as long. Caveat - I have not tried these with glutathione that I dissolved - only with saline, budosenide and levalbuterol.

The advantage of these is that they use the nebulizer cup of your choice, which can be sterilized easily at home.
Which nebulizer are you currently using?
