Refillable salt inhaller by Posergy
This has really, amazingly, helped me breathe better.  I have asthma, which makes me cough a lot.  Since using this I've hardly coughed at all.  I started with using it for 15-20 min. A day for three days.  Now I just use it if I feel I'm coughing too much.  Glad I found it.
