@ursala7 My experience is that the nebulizers start to leak after about 6 months or so. You can rotate the top of the aeroclipse from the arrow (with all the dots) to the arrow (solid-no dots) and the saline will just vaporize continuously. So, you will start to lose a lot of the saline. I have 8 aeroclipse nebulizers and 1 aerobika. I use the aerobika only to blow in (not inhale) after I nebulize with the aeroclipse. I soak in warm soapy water, rinse, and put aside and 2/week, I boil just the aeroclipse tops. The containers and mouthpieces, I put in the BOLOLO bottle sterilizer and disinfact that way. I know many put the aeroclipse tops in the BOLOLO, but I don't believe it has been proven to kill NTMs inside the aeroclipse. Jennifer Honda from UT-Tyler, did mention that they might get to-someday.
