Wow! In all these years somehow I missed this useful document.

For me, cleaning/sterilizing becomes one of the most challenging parts of traveling. The article states: "The appropriate means for cleaning and sterilising medical equipment (e.g. nebulisers and mucus-clearance devices) should be available when travelling", but it does not go into specifics. How did you deal with this aspect?

For domestic travel longer than a few days I pack a BBS along with a ramen pot for boiling water, dawn dish soap and a small silicone container. I'll pick up distilled water, which is easy to find in the US. In, Europe+ I understand finding distilled water is almost non-existent. The eFlow cleaning instructions specifically call for distilled water. What was your experience?
