I used to use one before I learned about Nebulizing Saline. It was not all that effective and no way to keep it sterile.

Dry salt inhaler is made by Nevelers. You can see it on their website and on Amazon. The results are strictly anecdotal and not medically supported. With that said, I quit nebulizing when a cavity was found in my right lobe and was growing. I switched to dry salt. My cavity collapsed within 3 months and the surgery was canceled. Coincidence? Maybe. I just didn’t feel that cold, wet mist inhaled into my lungs was doing me any good. So read about it and make your own decision. Best of luck to everyone.
