Full disclosure, I am rather fastidious. I make sure I have access to distilled water with something to boil it in, or, bring along a baby bottle sterilizer. There's another discussion in this forum about Control III solution for sterilizing eFlow but it remains murky whether that solution kills NTM. Control III is mentioned in the eFlow product insert under how to clean.

Regarding salt precipitation on counter, maybe there's a very small round bit of salt on a surface if I leave the nebulizer sitting before cleansing but I usually do not let it sit so that does not cause me trouble. Occasionally the nebulizer drips salt water on my shirt but since it's water soluble I simply wipe it off with a damp towel.

To your question:
"I’m reading all the posts and am wondering how the eFlow is faster, if you are needing to take multiple breaks ?"

Answer:
I practice airway clearance DURING nebulizing. I use the pause button a lot. Nebulizing and airway clearance are not separate activities for me, rather they are interwoven. OVERALL, it saves time for me, and in that way eFlow is faster. I find it more efficient and effective for me than separating nebulizing and airway clearance. Your mileage may vary!
