Does anyone know why and how the Pari e-rapid nebulizer seems to be so effective for people using it!! I’ve always been told that the smaller the particles of medicine and or saline are the deeper they get into the lungs. Now I also have bought numerous different nebulizers in the past 5 years, fighting my BE, as the years have passed it seems that they become less effective and efficient, and that’s even after purchasing new compressors and nebbing cups. I would love to try one but the nearly $1000 price tag holds me back!!! What if it doesn’t help?? Any thoughts or ideas would be appreciated. Bless us all with better breathing.
