Hi - thanks for your post and question - it's a good one! While I'm hopeful others in the community will see your inquiry and respond by sharing their own personal, anecdotal experiences using portable nebulizers, I have something to contribute as well.
As you pointed out, there are a wealth of commercially available portable nebulizers for patients to choose from Every patient has their favorites and I am sure, once you make a decision for yourself, you will find the nebulizer to be indispensable as well. I thought you might gain some additional insight from this article, by my good colleague, , which focuses on one aspect of the portable market: https://asthma.net/living/portable-nebulizers. I do hope you find the information is helpful for you.
All the best,
