I am not sure where I stand on this issue<img src="i/expressions/face-icon-small-smile.gif" border="0"> I will say I do have concerns about the cleaning that is recommended. For the AL study, we are told to clean with tap and dish soap and disinfect 1x per week with a special solution. Seems kind of odd. I think the cost is over the top too compared to a regular nebulizer. We really should have separate ones for each med and that is not very economical.
