We have a Pari compressor for our 18 month old. About 6 months ago it started to "act up". Meaning that it would take about 5-10 minutes to get warmed up before enough air would come through the nebulizer to adminster the medicine. It was very aggravating. So we called Pari and sent it back and they sent us a new one. Well, now its happening again! I have a back up compressor that I can use, but I was told the Pari was better because it gives out a finer mist of meds. I was just wondering if anyone else has had this kind of trouble with their Pari? Should I get a different brand?
