I also use a nebulizer and I have to haul it everywhere I go and I would have liked the smaller version but my insurance company doesn't want to pay for it. I checked on it a couple of years ago and it was expensive at that time.
Hi there - sorry I just saw your message.
I Googled "portable nebulizer" and there were some choices there - they are between $60-115 for the purchase, and the little bottles aren't very expensive. I think they give better delivery too than the atomizers..more relaxing.
Have a look see - I didn't think I should put the links up here because of the "spam factor".... but google has quite a selection of ads.
Happy breathing!!!
