I liked my Go, but it wasn't boilable (long story, rip little Go <img src="i/expressions/face-icon-small-wink.gif" border="0">). I had it for a nasal neb. I think you can get solutions to sterilize it, but I don't know what they are by name. It would need to be something that kills pa, aspergillus, mac, etc. You could contact the company you got it from- they should be able to tell you. Apparently, the ones that are sold in Europe<i> are </i>boilable, per the insert instructions- I'm waiting to get one of those <img src="i/expressions/face-icon-small-wink.gif" border="0"> .
