@thumperguy We've had nebulizers in our life foe almost 40 years between my kids, mom & me. Way back around the 90's we were told to remove the nebulizer cup from the tubing & hang the tubing after each use (mine is still attached to the compressor & is draped over the arm on my living room lamp a lot) to keep moisture from accumulating. My daughter goes one step further and runs her compressor a few minutes to pump dry air through. I figure no moisture, no bugs, but others may think differently. So unless I notice moisture, I don't usually clean it, but then it is with commercial cleaning-strength distilled vinegar.
The neb cup parts I clean in hot soapy water & scrub with a little brush used just for that after every use. Once every week or two it gets an alcohol bath for 30 minutes (now using vinegar as alcohol is scarce.) I was told by the respiratory therapist at our clinic to replace every 3-6 months depending on the frequency of use.
My philosophy is that MAC is slow to attach & slow to grow, so my periodic treatment plus regular replacement should be good. My biggest hesitation at adopting this plan was adding plastic to the waste stream...
What do others do?
