I also have the Ombra compressor and AeroEclipse XL nebulizer, both made by Monaghan, the same company that makes the Aerobika. You do not clean the Ombra, but you do change the filter monthly or when gray. I wash the nebulizer in warm, soapy water every time I use it. They suggest disinfecting every other day and give 5 options. I choose to soak in 1 part vinegar to 3 parts water for 1 hr., then rinse. I use the breath actuated mode, which I know takes longer, but I think I get more of the saline because it only produces aerosol when I inhale. What I haven't figured out is why I am able to nebulize 3 ml. Levalbuterol in a much shorter time period than 4 ml. saline. Does anyone have any thoughts on this?

I sterilize the cups daily and change the tubing and filter once a month. The machine itself is just wiped down.
